CQ2 / CDQ2 compact cylinder series
Coverage CQ2/CDQ2 covers the standard compact-cylinder function; large-bore compact variants extend to 200mm; companion non-rotating (CDQ2K) and double-rod configurations cover orientation control; SMC's separate guided-cylinder lines handle side-load duty. Single-acting (spring extend/return) options available. No NSF or ATEX variant in the standard CQ2 line.
The CQ2 (CDQ2 with magnet) is SMC's standard compact cylinder and one of the highest-volume cylinders SMC sells — a double-acting, single-rod round-body cylinder with a very large standard-option set (mount styles, rod ends, switch positions on all four faces). Bore 12mm-100mm with large-bore variants to 200mm; standard strokes to 300mm with intermediate strokes via internal spacers.
Why SMC here When an OEM print specifies SMC, CQ2 is the matching compact cylinder, and its broad standard-option set and fast delivery across bore/stroke combinations make it the recognized benchmark for spec'd-in small automation.
D-series auto-switches — solid-state D-M9 family (D-M9N/M9P/M9B); reed-switch D-A9 family (D-A90/A93/A96, plus perpendicular-exit D-A90V/A93V/A96V)
Coverage Solid-state vs. reed-switch is the primary variant: D-M9 solid-state for high-cycle and long-life duty; D-A9 reed for lower-cycle, cost-sensitive duty. Within the D-A9 reed family the three model designations are D-A90 (2-wire, no indicator light), D-A93 (2-wire, with indicator light), and D-A96 (3-wire, with indicator light), each available in a standard in-line lead exit or a perpendicular "V" lead exit (D-A90V/D-A93V/D-A96V). Solid-state output variants: 3-wire NPN (D-M9N), 3-wire PNP (D-M9P), 2-wire (D-M9B); normally-open standard. Lead variants: pre-wired cable in 0.5 m (Nil), 1 m (M), 3 m (L), and 5 m (Z) lengths, or M8 / M12 connector models for field-made runs. Mounting variants match SMC's cylinder families — band, rail, tie-rod and direct/groove mounting styles; the D-A9V perpendicular-exit variant cannot be band-mounted. IO-Link-compatible D-series models are available where position data must join a smart valve terminal network.
SMC's cylinder position sensors are the D-series auto-switch range. The current general-purpose solid-state line is the D-M9 family — D-M9N (3-wire NPN), D-M9P (3-wire PNP), and D-M9B (2-wire) — with an LED operating indicator. The reed-switch line is the D-A9 family, in three discrete models: D-A90 (2-wire, no indicator light), D-A93 (2-wire, with red indicator light, for relay/PLC loads, 24 VDC), and D-A96 (3-wire, with indicator, for IC-circuit loads, 4-8 VDC). Each is also offered in a perpendicular lead-exit "V" variant (D-A90V/D-A93V/D-A96V). D-A9 reed switches cover lower-cycle, cost-sensitive duty. SMC auto-switches are designed to drop into the mounting groove or band of the matching SMC cylinder series and read that cylinder's piston magnet; IO-Link-capable D-series models report position on a network.
Why SMC here The position sensor must match the cylinder it mounts to, and SMC's D-series is engineered to seat directly into the groove or band of SMC's own cylinder series — so on an SMC-based machine the D-series auto-switch is the direct, no-adapter fit. The D-M9 line covers both reed and solid-state needs across a single mounting standard, which keeps a plant's sensor inventory consistent.
Series-specific cylinder seal kits — CQ2 (CQ2B-PS / CQ2BH-PS), MB / MB1 / CA2 (MB-PS / MB1-Z-PS / CA2K-PS family), MY1 rodless (MY1B-PS / MY1M-PS), NCA1 tie-rod (configurable NCA1-...-PS); C85 round-body and C96/CP96 ISO families also offered, kit numbers not yet datasheet-confirmed
Coverage Seal kits cover SMC's main cylinder construction families with bore-specific contents. Verified part numbers from the SMC cylinder catalogs: CQ2 compact cylinder — CQ2B12-PS through CQ2B100-PS (pneumatic, bores 12-100 mm) and CQ2BH20-PS through CQ2BH100-PS (air-hydro, bores 20-100 mm). MB / CA2 air cylinder — MB32-PS through MB125-PS (standard, bores 32-125 mm), MBW32-PS through MBW100-PS (water-resistant), MBK32-PS through MBK100-PS (non-cushion); the CA2 cast cylinder's seal kits are published under MB-PS / MBW-PS / CA2K-PS / CA2KW-PS numbers (CA2K40-PS to CA2K63-PS, CA2KW40-PS to CA2KW63-PS for the non-rotating variant). MB1 air cylinder — MB32Z-PS, MB1-40Z-PS through MB1-100Z-PS, MB125-PS (standard) and MBW32Z-PS, MB1W40Z-PS through MB1W100Z-PS, MBW125-PS (water-resistant). MY1 rodless cylinder — MY1B10-PS through MY1B100-PS (basic) and MY1M16-PS through MY1M63-PS (slide-bearing/high-precision). NCA1 NFPA tie-rod cylinder — seal kit is configured: ordered as NCA1-[W for double rod]-[bore 150/200/250/325/400]-PS. Cushioned cylinders take kits that include cushion seals. [VERIFY] C96/CP96 ISO 15552 seal kits and C85 round-body kits — not in the on-disk SMC catalogs; resolve from the SMC maintenance-parts list or seal-kit search tool.
SMC publishes a standard seal kit for each cylinder series, keyed to the cylinder construction family and bore. Every SMC cylinder catalog carries a Replacement Parts / Seal Kit table in its construction section, and the kit part number is ordered against the bore size shown on the cylinder nameplate. Confirmed from SMC cylinder catalogs: the CQ2 compact cylinder uses CQ2B-PS kits by bore (pneumatic) and CQ2BH-PS kits (air-hydro); the MB and MB1 air cylinders use MB-PS / MB1-Z-PS kits; the CA2 cast cylinder shares the MB-PS kit family; the MY1 rodless cylinder uses MY1B-PS / MY1M-PS kits; and the NCA1 NFPA tie-rod cylinder uses a configurable seal kit ordered as NCA1-[option]-[bore]-PS. Each kit consists of the wear ring, rod seal, piston seal, cushion seal and tube gasket for that bore, and most kits include a grease pack. SMC's online seal-kit search tool returns the correct kit from the full cylinder model number.
Why SMC here When the installed cylinder is SMC, the SMC seal kit is the exact-match repair — bore-specific, engineered to the cylinder's seal grooves, and identifiable directly from the cylinder model number through SMC's maintenance-parts catalog.
LE-series electric actuators — LEY / LEYG rod & guide-rod, LEF / LEFS slider, LEPY / LEPS miniature, LER rotary, LEH gripper; LECP / LECA / JXC controllers
Coverage LEY covers the rod-type core across sizes 25, 32, 63 and 100; LEYG is the guide-rod variant for loads that must not rotate or that carry side load. LEF/LEFS covers slider/table motion; LEPY (miniature rod) and LEPS (miniature slide table) cover compact precision work; LER covers rotary-table motion; LEH covers electric gripping. A motorless LEY/LEYG option lets a customer fit their own motor or standardized controls package. Step-motor builds at the smaller sizes provide a lower-cost 24 VDC alternative to the AC-servo builds. Electric actuators are generally not washdown- or hazardous-location-rated; an axis in a wet or classified environment is better served by SMC's pneumatic cylinder lines.
SMC's electric-actuator line is the LE-series, a coordinated family whose body styles mirror the pneumatic-cylinder families. The rod-type LEY is the core: a ball-screw rod actuator built to substitute for a standard pneumatic cylinder. The verified LEY range spans frame sizes 25 and 32 (100/200 W AC servo, up to 500 mm stroke, 60 kg horizontal / 46 kg vertical work load, 736 N maximum pushing force), the high-output LEY63 (400 W AC servo, up to 800 mm stroke, 200 kg horizontal / 115 kg vertical work load, 1,910 N pushing force), and the largest LEY100 (750 W AC servo, 100 to 1000 mm stroke, up to 1,200 kg horizontal / 200 kg vertical work load with an external guide, 12,000 N maximum pushing force). Positioning repeatability is ±0.02 mm (±0.01 mm high-precision option on LEY63). Each size offers several ball-screw leads so force and speed can be optimized to the application — LEY100 is offered in 10 mm, 3.3 mm and 2 mm lead — and motors are available with 17-bit incremental or 18-/20-/22-bit absolute encoders. SMC's separate controllers are the required companion: LECP1 programless (14 positions, panel-set, no PC), LECP6/LECA6 step-data (up to 64 PLC-called positions), and JXC fieldbus (EtherNet/IP, PROFINET, EtherCAT and others) for networked machines.
Why SMC here SMC's LE-series lets a customer move a precision axis to electric without leaving the brand already on their pneumatic bill of materials — the rod-type LEY is designed to substitute for a pneumatic cylinder's footprint, and the controller tiers run from a no-programming programless unit up to full fieldbus integration, so the line meets a shop wherever it sits on the electric-adoption curve. One brand and one support path across both pneumatic and electric motion.
AW-D series modular filter-regulators
Coverage AW-D covers the filter-regulator function across SMC's modular body sizes; transparent and metal bowls; manual and auto drains; standard and tamper-resistant knobs; 125 PSI max set pressure. For tighter regulation accuracy SMC's separate IR precision-regulator line is used. No ATEX or NSF variant in the standard AW-D line.
SMC's filter-regulator is the AW-D modular series — a combined filter and regulator in one compact body for installations with limited air-prep space, with a 125 PSI maximum set pressure and SMC's standard modular feature set. AW-D joins the same AC-D modular family, so an FR can later gain a lubricator module without re-piping.
Why SMC here When an OEM print specifies SMC, the AW-D is the matching filter-regulator — it integrates with the rest of an SMC-based machine and is the recognized benchmark for spec'd-in automation.
AC-D series modular F.R.L. combination units (legacy AC series also in service)
Coverage AC-D covers F+R+L and F+R builds across body sizes 20/30/40; transparent and metal bowls; manual and auto drains; standard and tamper-resistant regulator knobs. Maximum set pressure 125 PSI on the AC-D modular line; the older AC series adjusts higher. No ATEX or NSF FRL combo in the standard AC-D line.
SMC's combination air-prep units are the AC-D modular series — body sizes 20/30/40, ports roughly 1/8" to 1", maximum set pressure 125 PSI. The AC-D format clamps a filter, regulator, lubricator, mist separator, pressure switch, or shut-off valve together in any combination, so an F+R+L or an F+R is assembled from one modular family rather than a fixed casting. SMC is the pneumatics brand most often written onto OEM machine prints.
Why SMC here SMC is the global pneumatics benchmark and the brand most often specified by automation engineers on machine prints — when a print calls for SMC, this is the matching unit, and the AC-D family integrates cleanly with SMC valves and cylinders elsewhere on the same machine.
Service items for SMC modular air-preparation equipment — AC-D combination units, AW-D filter-regulators, AF-D filters, AR-D regulators, AL-D lubricators, AFM-D / AFD-D mist separators
Coverage Datasheet-verified service parts from the AC_New FRL catalog. AF-D air filter: filter element AF20P-060S / AF30P-060S / AF40P-060S / AF50P-060S / AF60P-060S; baffle AF24P-040S / AF34P-040S / AF44P-040S / AF54P-040S / AF64P-040S; bowl seal C2SFP-260S / C32FP-260S / C42FP-260S. AR-D regulator: valve assembly AR24P-060AS / AR34P-060AS / AR44P-060AS / AR49P-060AS / AR54P-060AS / AR64P-060AS; diaphragm assembly in relieving type AR24P-150AS / AR34P-150AS / AR44P-150AS / AR54P-150AS and non-relieving type AR24P-150AS-N / AR34P-150AS-N / AR44P-150AS-N / AR54P-150AS-N; valve guide assembly AR24P-050AS / AR34P-050AS / AR44P-050AS / AR54P-050AS; check valve assembly AR24KP-020AS for AR-K backflow variants. Filter elements come in general-purpose (5 micron, AF) and coalescing (0.3 / 0.01 micron, AFM/AFD) grades; bowl assemblies are stocked by bowl material (polycarbonate, metal), drain mechanism (manual drain cock, auto drain N.C./N.O.) and port style, each with a bowl seal. [VERIFY] explicit per-size bowl-assembly part numbers and the AFM/AFD and AL-D element numbers — the catalog cross-references separate per-series tables for these; resolve against the SMC maintenance-parts list to close fully.
SMC supports its AC-D modular air-preparation family with replacement filter elements, valve and diaphragm assemblies, bowl assemblies, bowl seals, baffles, and drain parts. Because the AC/AW/AF/AR/AL units share one modular family, service items are keyed to the specific element being serviced. SMC's part-numbering follows a consistent pattern: the body model prefix carries through to the service part — an AF40-D filter takes the AF40P-060S filter element, an AR40-D regulator takes the AR44P-060AS valve assembly. The maintenance-parts catalog returns the correct element and seal set from the unit's model number.
Why SMC here When the installed FRL is SMC, the SMC service kit is the exact-match consumable — the filter element grade and bowl gasket are engineered for the AC-D body, so the serviced unit holds its original filtration rating and seal integrity. The modular family makes the right service item easy to identify from the unit label.
CA2 / CDA2 air cylinder series
Coverage CA2/CDA2 covers the heavy-duty standard function; SMC offers a clean-room build of the CA2 for controlled environments and rod-boot / heat-resistant seal options for abrasive and high-temperature service; non-rotating and double-rod configurations available. Larger-bore and higher-force severe-duty work above the CA2 range routes to the NFPA tie-rod line.
SMC's heavy-duty cylinder is the CA2 (CDA2 with magnet) series — a robust tie-rod air cylinder in bores 40, 50, 63, 80, and 100mm with standard strokes to 500mm, built for standard-to-severe industrial duty. It carries adjustable air cushioning and a full mount-style range.
Why SMC here When an SMC-based machine needs a robust standard cylinder for heavier or dirtier duty, CA2 is the matching heavy-duty line and integrates with the rest of an SMC pneumatic system.
EX600 modular fieldbus / IO-Link platform
Coverage EX600 mounts SMC's SY series (current), and the SV1000/2000/3000, VQC1000/2000/4000, and S0700 valve series — so an EX600 terminal can be built around the SMC valve series already specified on a machine. Fieldbus variants are firmware-specific and selected per PLC: EtherNet/IP, PROFINET, EtherCAT, DeviceNet, CC-Link / CC-Link IE Field, PROFIBUS-DP, POWERLINK. Enclosure variants: standard panel-grade rating for in-cabinet mounting, and a sealed IP67-class variant for on-machine and washdown installations. A handheld terminal and the EX600-T input terminal unit extend the platform. EX600 is not a safety-rated terminal — safety-category applications need dedicated safety valves.
SMC's smart valve terminal is the EX600 modular platform — a fieldbus and IO-Link gateway that mounts on SMC's solenoid valve manifolds and brings the valve bank onto the plant network through one connection. The EX600 gateway carries an IO-Link master plus the plant fieldbus interface; up to four IO-Link modules and 16 IO-Link devices connect per manifold, and the platform supports a large mixed I/O count across input, output, and analog modules. It reports per-valve cycle counts, valve-state confirmation, coil diagnostics, supply-voltage health, and manifold temperature. EX600 is the SMC product that carries the Industry 4.0 / predictive-maintenance conversation.
Why SMC here SMC is the global pneumatics benchmark, and EX600 is its established smart valve terminal — the natural match for an SMC-based machine, since it mounts the SY/VQC valve series an SMC-spec'd machine already uses and adds the diagnostic layer without changing the valves. For a plant moving toward IIoT, EX600's broad fieldbus coverage and mature IO-Link implementation make it a low-risk first step into smart pneumatics.
C96 / CP96 ISO 15552 cylinder series (formerly C95)
Coverage C96/CP96 covers the standard ISO 15552 function across the 32-125mm bore range; CP96K covers the non-rotating-rod variant; double-rod and oversized-rod options available; the C95 large-bore interchange line extends above 125mm. No NSF variant in the standard line; SMC's separate stainless / clean-series and ATEX-rated cylinder lines cover food and hazardous-location duty.
SMC's ISO 15552 cylinder is the C96 / CP96 series — a tie-rod-construction profile cylinder, ISO 15552 and VDMA 24562 interchangeable, in standard bores 32, 40, 50, 63, 80, 100, and 125mm. It uses a floating cushion-seal design for smooth end-of-stroke deceleration. The earlier C95 designation remains in SMC's US interchange-type catalog for large-bore service; C96/CP96 is the current ISO 15552 line.
Why SMC here When an OEM print specifies SMC for ISO 15552, C96/CP96 is the matching cylinder — it integrates with the rest of an SMC-based machine and is the recognized benchmark for spec'd-in, high-cycle automation.
AL-D series modular lubricators (standard-fog / mist-type)
Coverage AL-D modular lubricator in body sizes 20 through 60. Minimum dripping flow rate by size: AL20 15 L/min (ANR); AL30 30 L/min at 1/4" port and 40 L/min at 3/8" port; AL40 30 L/min at 1/4", 40 L/min at 3/8", 50 L/min at 1/2" port; AL40-06 50 L/min; AL50 190 L/min; AL60 220 L/min — all per ISO VG32 oil at 0.5 MPa inlet, 20°C, oil valve fully open. Oil capacity 25 / 55 / 135 cm3 across the body sizes. Polycarbonate bowl with steel or polycarbonate bowl guard; adjustable drip rate. Note: the AC_New FRL catalog lists only the standard-fog AL-D — it carries no standard-fog versus micro-fog split for this series. SMC's micro-fog lubricator is a separate model line, not the AL-D.
SMC's standalone lubricator is the AL-D modular series, clamping into the same AC-D / AW-D / AR-D modular family so a lubricator stage can be added to an existing FR train without re-piping. It uses an adjustable oil drip rate with a sight dome for the oil level. Recommended lubricant is Class 1 turbine oil (ISO VG32). The AL-D is a mist-type (standard-fog) lubricator; the catalog rates each size by minimum dripping flow rate — the minimum air flow needed to draw oil — rather than by a fog grade.
Why SMC here When a machine that genuinely requires lubricated air is built on SMC, the AL lubricator matches the rest of the air-prep train stage-for-stage and is the spec'd-in benchmark.
SY-series manifold valves on SS5Y manifold bases (SS5Y3/5/7); EX260 / EX600 fieldbus manifold platforms
Coverage SS5Y bases carry mixed 5/2 single, 5/2 double, 5/3, and 3/2 SY stations on one manifold, typically 2–24+ stations. Electrical-connection variants: individual wiring, D-sub, flat ribbon, and EX260/EX600 fieldbus output blocks. IP40 to IP67 by base type. The EX260/EX600 fieldbus and IO-Link configurations are the connected/smart-terminal variant — covered under the Smart Valve Terminal product type.
SMC's SY-series valves mount onto the SS5Y manifold base family (SS5Y3, SS5Y5, SS5Y7) in side- and bottom-ported configurations. Manifold electrical connection ranges from individual wiring and D-sub multi-pin connectors to the EX260 and EX600 integrated serial-transmission (fieldbus) systems at IP67. The EX600 platform supports SV1000/2000/3000, VQC1000/2000/4000, S0700, and the new SY series.
Why SMC here SMC's SS5Y manifold system is widely specified on OEM machines and configures a single base to a machine's exact per-station function list; manifold spec'ing on this platform is genuine engineering support SPC's DC reps provide, and it carries forward cleanly to the EX600 fieldbus platform if a customer later adds connectivity.
VM mechanical valves (VM1000 micro, VM100, VM200 — 2/3-port); VFM pilot-operated 5-port mechanical valves (VFM300/VFM350 rubber seal, VFM200/VFM250 metal seal); VH hand valves (VH200/300/400/600)
Coverage VM covers 2/3-port mechanical valves across three size classes (VM1000 micro, VM100, VM200) with actuator style as the primary configuration choice — roller/straight/cross-roller plungers, lever and toggle-lever, push buttons in four button colors, twist and key selectors, and a VM200-only foot pedal; side-ported and bottom-ported piping and bracket/panel mounting are selectable. VFM covers pilot-operated 5-port (5/2) mechanical valves in rubber-seal (VFM300/VFM350) and metal-seal (VFM200/VFM250) builds with internal or external pilot. VH hand valves cover manual 2/3-port shutoff and selector control in body-mount or panel-mount form across VH200/300/400/600 sizes. The earlier research-note references to SMC "NV" and "VK" mechanical-valve series are not current SMC family names and are not in any SMC valve catalog — they are removed. VM, VFM, and VH are the verified current families; VHL is the lockout-valve family name but is unverified from the supplied datasheet.
SMC's mechanical and hand-operated valve range is built on three families. The VM mechanical valve covers 2/3-port valves in three size classes — VM100 and VM200 (2/3 Port Mechanical Valve) and the miniature VM1000 (Micro Mechanical Valve) — with the widest spread of actuator styles in the line: roller lever, roller plunger, straight plunger, cross roller plunger, one-way roller lever, toggle lever, push buttons (flush, mushroom, extended), twist selectors (2- and 3-position), key selector (2-position), and a foot pedal on VM200. VM100 handles vacuum to pressure work over a -100 kPa to 1 MPa range. The VFM series is a pilot-operated 5-port mechanical valve in rubber-seal (VFM300, ordering code VFM350) or metal-seal (VFM200, ordering code VFM250) construction, rated to 300 c.p.m. with internal or external pilot body options. The VH series is a manually operated hand valve (2/3-port shutoff and selector duty) in body-mount and panel-mount builds across VH200/300/400/600 size classes, rated to 1.5 MPa air. Note: SMC also catalogs a VHL lockout valve, but the supplied VHL datasheet contains no extractable specification text — VHL detail is not datasheet-verified beyond the model name.
Why SMC here SMC offers the broadest mechanical-valve actuator range of the portfolio brands — lever, button, palm, foot pedal, and roller — so a single brand covers operator-station, safety-stop, and end-of-stroke sequencing needs, and matches the rest of an SMC-based machine.
NCA1 / NCDA1 NFPA interchangeable air cylinder series
Coverage NCA1/NCDA1 covers the NFPA function across medium-duty (1.5"-4", expanded to 8") and heavy-duty (to 14") construction grades; double-rod, non-rotating-rod, and oversized-rod options available; large-bore configurations serve press and forming duty. Rebuild kits stocked as a service item.
SMC's NFPA tie-rod cylinder is the NCA1 (NCDA1 with magnet) series — an NFPA-interchangeable, tie-rod air cylinder. The medium-duty line covers 1.5"-4" bore (with an expanded medium-duty range to 8"); the heavy-duty range spans 1.5" up to 14" bore. It is field-rebuildable, available in 11 mounting styles, and SMC stocks seal rebuild kits.
Why SMC here When a North American machine needs an NFPA tie-rod cylinder — new build or a dimensional retrofit of an existing tie-rod cylinder — NCA1 is the matching SMC line, field-rebuildable and backed by stocked rebuild kits for recurring service.
MB1K / CM2K non-rotating-rod air cylinder series
Coverage Non-rotating-rod (K) variants are available across SMC's MB1, CM2, and CQ2 cylinder families rather than as a single stand-alone line — so the bore range and body style are chosen first, then the non-rotating rod option specified. Double-rod and double-acting forms available. For applications needing side-load support as well as anti-rotation, SMC's guided-cylinder lines are the alternative.
SMC offers non-rotating-rod cylinders as a configuration of its standard air-cylinder families — the MB1K (bores 32-125mm, MB1 family) and the smaller-bore CM2K (CM2 family). The K designation marks the non-rotating-rod variant, which holds the rod at a fixed angular orientation through the stroke.
Why SMC here When an SMC-based machine needs a rod that holds orientation — parts handling, pick-and-place — the matching MB1K / CM2K non-rotating variant comes from the same cylinder family already used elsewhere on the machine, keeping mounting and switches consistent.
RB series, 8 models RB0805-RB2725 (standard self-adjusting); RBL series, 6 models RBL1006-RBL2725 (coolant-resistant); RBQ series, 5 models RBQ1604-RBQ3213 (short type); RJ series (soft type)
Coverage RB standard series — eight models, verified from the SMC RB engineering datasheet (figures are max energy absorption J / stroke absorption mm / max operating frequency cycle/min / max allowable thrust N): RB0805 0.98 J / 5 / 80 / 245; RB0806 2.94 J / 6 / 80 / 245; RB1006 3.92 J / 6 / 70 / 422; RB1007 5.88 J / 7 / 70 / 422; RB1411 14.7 J / 11 / 45 / 814; RB1412 19.6 J / 12 / 45 / 814; RB2015 58.8 J / 15 / 25 / 1961; RB2725 147 J / 25 / 10 / 2942. RBL coolant-resistant series, six models: RBL1006 3.92 J / 6 / 70 / 422; RBL1007 5.88 J / 7 / 70 / 422; RBL1411 14.7 J / 11 / 45 / 814; RBL1412 19.6 J / 12 / 45 / 814; RBL2015 58.8 J / 15 / 25 / 1961; RBL2725 147 J / 25 / 10 / 2942 (RBL shares RB energy ratings but carries higher spring force). RBQ short series, five models: RBQ1604 1.96 J / 4 / 60 / 294; RBQ2007 11.8 J / 7 / 60 / 490; RBQ2508 19.6 J / 8 / 45 / 686; RBQ3009 33.3 J / 8.5 / 45 / 981; RBQ3213 49.0 J / 13 / 30 / 1177. All three series collide at 0.05-5.0 m/s (RBQ 0.05-3.0 m/s); each model offers a basic type and a with-cap type (RBC / RBLC / RBQC) plus an optional stopper nut. RJ soft type covers M6-M27 in three absorbed-energy classes of roughly 1, 3, and 10 J with stroke 6 / 7 / 12 mm. [VERIFY] RJ per-model figures — not in the RB or RBQ engineering datasheets; resolve against the SMC RJ datasheet.
SMC's shock absorbers are self-adjusting hydraulic absorbers — a specially designed orifice automatically delivers appropriate absorption from high-speed light loads to low-speed heavy loads with no external tuning. The RB series is the standard line; RBL is the coolant-resistant variant (effective in non-water-soluble cutting oil, with a heavier spring force); RBQ is the short/compact-body line, shortened lengthwise with a 5-degree allowable eccentric angle so it can be positioned directly without an external stopper. The RJ series is the soft type, profiled with a spiral-groove orifice to stop light loads at low speed gently. All series share a 0.05-5.0 m/s collision-speed range (RBQ 0.05-3.0 m/s) and a -10 to 80°C ambient range. Max operating frequency is the value at maximum energy absorption per cycle — cycle rate can be increased proportionally when less energy is absorbed.
Why SMC here Where an OEM machine print specifies SMC, the RB and RJ series are the matching shock absorbers — they keep end-of-stroke protection consistent with the rest of an SMC-based machine and avoid a compatibility question on a spec'd-in design. SMC's self-adjusting orifice also means one part number covers a span of load-and-speed conditions, simplifying selection on stable lines.
ITV electro-pneumatic regulator series (ITV0000 / ITV1000 / ITV2000 / ITV3000; ITV009x electronic vacuum regulator)
Coverage [VERIFY against the current SMC ITV catalog — research-incomplete category] Body-size variants: compact ITV0000, then ITV1000 / 2000 / 3000 stepping up in flow capacity and port size. Function variants: positive-pressure electro-pneumatic regulators, plus the dedicated ITV009x electronic vacuum regulator. Input-signal variants: analog voltage and analog current models, preset-step models, and digital / networked models (fieldbus-interfaced ITV versions, including Ethernet-capable units). Set-pressure ranges step by model up to roughly 125–130 PSI on the standard positive-pressure lines. Exact per-model pressure range, flow, accuracy, and port size to be confirmed against the ITV datasheet.
[VERIFY — proportional-regulator category research is incomplete; the figures below are from the SMC ITV catalog and must be confirmed before customer use] SMC's proportional pressure regulator is the ITV electro-pneumatic regulator series. The ITV gives stepless control of output pressure in proportion to an electrical input signal, with internal closed-loop feedback. The series spans a compact ITV0000 line, the main ITV1000 / 2000 / 3000 bodies in ascending flow capacity, and an ITV009x electronic vacuum regulator for negative-pressure control. Published ITV figures cite a linearity around ±0.5% of full scale and an IP65-equivalent rating.
Why SMC here SMC's ITV is a long-established, widely specified electro-pneumatic regulator line with broad body-size and signal-type coverage — positive-pressure and vacuum, analog and networked — so a single brand can serve tension-control, force-control, and test-stand applications across a plant. On an SMC-based machine it integrates with the rest of the SMC air-preparation and control lineup.
IDFB series refrigerated air dryers + replacement parts (auto drains, solenoid valves, dust-collecting filter sets)
Coverage 10–459 CFM, 3/8"–2" NPT, 115/230/460V 1- & 3-Phase, R134a/R407C/R410A, up to ~100 HP compressors
Non-cycling refrigerated dryers with stainless steel heat exchanger; install vertical, require 1-micron pre-filter.
Why SMC here SMC's IDFB-series refrigerated dryers bring a stainless-steel heat exchanger to the standard non-cycling design — a corrosion-resistant core that holds up over a long service life. The range runs 10 to roughly 459 CFM across single- and three-phase power and three refrigerant options, covering compressors up to about 100 HP from one series. For accounts already standardized on SMC pneumatics, the dryer keeps air treatment on a brand their maintenance team already knows and stocks parts for, with auto drains, solenoid valves, and dust-collecting filter sets available as matched replacement items.
ZP / ZP2 / ZP3 suction-cup series (replacement pads)
Coverage ZP-family cups cover the cup designs taught in the Product Type — flat, flat-with-rib, deep, bellows (plus oval and multi-bellows special variations) — in the six ZP2 pad materials covering NBR, silicone, urethane, FKM/fluorosilicone and conductive/anti-static and mark-free compounds, across the ZP/ZP2/ZP3 diameter ranges (ZP2 = 2-340 mm). A worn cup is replaced like-for-like by matching the existing diameter, design, and material code, or material-upgraded (for example to urethane for abrasive high-cycle picks) while staying within the family. [VERIFY] exact ZP-series replacement-cup part numbers by diameter, style, and material — the SMC USA suction-cup page does not publish the part-number tables; this requires the full SMC vacuum-pad catalog.
SMC's ZP-family suction cups are a full line of replacement vacuum cups covering the gripping interface for pick-and-place tooling. The ZP series is the general-purpose line; ZP2 is the broad current family, 2-340 mm diameter, built on four core cup designs (flat, flat with ribs, deep, bellows) in six pad materials plus special variations (miniature, compact, nozzle, multi-bellows, sponge, mark-free, oval, heavy-duty); ZP3 is the compact family with a shortened buffer body. SMC publishes grip-force and cup dimensional data, so a replacement is sized and matched rather than guessed. Replacement-cup ordering: the pad itself is a sub-option of the family part number selected by diameter + design + material, with the buffer/adapter ordered separately or as a cup-with-buffer assembly.
Why SMC here When the installed cup is an SMC ZP, the SMC replacement is the direct match — it fits the existing end-of-arm tooling and mounting, and SMC's published grip-force data lets a worn cup be replaced or material-upgraded with confidence rather than by trial and error. It also keeps a vacuum circuit consistent with SMC cylinders and valves already on the machine.
MY1 mechanically jointed rodless cylinder series
Coverage MY1 covers the rodless function across basic, slide-bearing, and ball-bearing linear-guide-integrated types — the MY1B basic type, plus guided / high-rigidity variants (e.g. MY1H) for higher carriage load and moment capacity. Stroke-adjuster and shock-absorber options handle end-of-stroke control. Mid-span barrel support recommended on long strokes.
SMC's rodless cylinder is the MY1 series — a mechanically jointed rodless cylinder where the carriage is coupled to the piston through a sealing band. The MY1B basic type covers bores 16, 20, 25, 32, 40, 50, 63, 80, and 100mm with strokes to 5,000mm; the MY3 series adds bores 16, 25, 40, and 63mm.
Why SMC here When an SMC-based machine needs a long-stroke axis in a short installed envelope, MY1 is the matching rodless line, with guided variants that scale carriage load capacity to the application.
CRA1 rack-and-pinion and CRB2 vane rotary actuator series
Coverage The vane line (CRB2/CRBU2) covers compact rotary motion; single-vane gives the larger swing angle, double-vane gives higher torque at a smaller angle. The rack-and-pinion line (CRA1) covers higher-torque, higher-accuracy applications. Adjustable-angle and table / through-shaft output options available; adjustable end-of-rotation cushioning on standard units.
SMC's rotary actuators cover both mechanisms: the CRA1 (CDRA1 with magnet) rack-and-pinion series in sizes 30, 50, 63, 80, and 100, for high torque-to-size and accurate end positioning; and the CRB2 / CRBU2 vane series for compact direct rotary motion. Standard angles include 90, 180, and 270 degrees.
Why SMC here When an SMC-based machine needs a set-angle rotary motion, SMC covers both the vane and rack-and-pinion mechanisms in one brand, so the actuator can be matched to the torque-and-accuracy need without leaving the machine's existing pneumatic system.
SY series (SY3000 / SY5000 / SY7000) 5-port pilot solenoid valves; legacy SV and VQC series for existing installs
Coverage SY covers 5/2 single solenoid, 5/2 double solenoid, 5/3 (closed / open / pressure center), and 3/2 across SY3000/5000/7000. Coil voltages 12/24 VDC and 100/110/200/220 VAC. Rubber-seal and metal-seal options; internal or external pilot. Body-ported (inline) and base/manifold-mounted forms. The SY platform also seats onto SMC's SS5Y manifold bases and EX-series fieldbus/IO-Link terminals.
SMC's SY series is the current-generation 5-port pilot solenoid valve, offered body-ported or base-mounted across three body sizes. The redesigned SY3000/SY5000 increased flow by up to 80% within the prior valve width. A built-in pilot strainer guards against foreign matter and H-NBR seals improve ozone resistance. Rated cycle life is roughly 70 million cycles on the rubber-seal construction and 200 million on the metal-seal construction; response time is roughly 15 ms (SY3000) to 32 ms (SY5000) at 0.5 MPa.
Why SMC here SMC is the global pneumatics benchmark and the brand most often named on OEM machine prints; when a print or engineer specifies SMC, the SY series is the matching solenoid valve and integrates with the rest of an SMC-based machine and manifold. Its metal-seal cycle-life rating suits high-cycle, continuous-duty automation.
AF-D series modular air filters (AFF-D line filter, AFM-D / AFD-D mist separators; modular-connection generation re-designates these AFF / AM / AMD)
Coverage AF-D general-purpose filter, 5 micron nominal rating, drain capacity 8 / 25 / 45 cm3 by body size, polycarbonate bowl with steel or polycarbonate bowl guard, manual or auto drain (N.C. and N.O.). AFF-D line filter, 1 micron nominal rating at 99% efficiency, max flow capacity 300 / 750 / 1500 / 2200 / 3700 L/min (ANR) for body sizes 20 through 60. AFM-D mist separator, 0.3 micron nominal rating at 99.9% efficiency, outlet oil-mist concentration max 1.0 mg/m3, max flow capacity 200 / 450 / 1100 L/min (ANR) for sizes 20 / 30 / 40. AFD-D micro mist separator, 0.01 micron nominal rating at 99.9% efficiency, outlet oil-mist concentration max 0.1 mg/m3, max flow capacity 120 / 240 / 600 L/min (ANR) for sizes 20 / 30 / 40. In the modular-connection generation the equivalents are AM (0.1 micron, max flow 300 / 750 / 1500 / 2200 / 3700 L/min ANR) and AMD (0.01 micron, same flow band). Transparent and metal bowls; manual and auto drains. Activated-carbon oil-vapor removal is a separate SMC element.
SMC's standalone filter family covers four filtration stages. The AF-D general-purpose air filter removes particulate and bulk liquid at a 5 micron nominal rating. The AFF-D line filter steps that to a 1 micron nominal rating (99% efficiency) with a 99% water-droplet removal ratio. The AFM-D mist separator removes fine oil aerosol to a 0.3 micron nominal rating, and the AFD-D micro mist separator reaches 0.01 micron — coalescing-grade. All four are modular bodies that clamp into the same AC-D / AW-D family. Note: SMC's current modular-connection generation re-designates the line-filter stages as AFF (1 micron line filter), AM (0.1 micron mist separator) and AMD (0.01 micron micro mist separator).
Why SMC here When a machine is built on SMC, the AF filter line matches it stage-for-stage and is the benchmark for spec'd-in automation, with a clear path from general particulate to coalescing-grade filtration in one modular family.
AR-D series modular regulators (relieving standard, non-relieving option, AR-K backflow variant); IR series precision regulators
Coverage AR-D general-purpose modular regulator, set pressure range 0.05 to 0.85 MPa, standard and tamper-resistant (key-lockable) knobs, downward or upward knob orientation, left-to-right or right-to-left flow, panel and inline mounting. Relieving type is standard; the non-relieving build is an option on the same body (exhaust-mechanism code N), with a dedicated non-relieving diaphragm assembly stocked as a service part (AR24P-150AS-N / AR34P-150AS-N / AR44P-150AS-N / AR54P-150AS-N by size). A backflow-function variant, AR-K, is offered with a check-valve assembly. The IR series covers precision regulation for instrumentation, paint and lab use. Note: the AR-D modular catalog does not list a dedicated pilot-operated or "high-flow pilot-operated" AR model — pilot-operated regulation is outside the AR-D modular line and would need a separate SMC regulator series.
SMC's standalone regulator is the AR-D modular series — set pressure range 0.05 to 0.85 MPa (roughly 7 to 125 PSI), max operating pressure 1.0 MPa, with SMC's standard modular feature set, clamping into the same AC-D / AW-D family. The AR-D ships relieving type as standard; a non-relieving build is selectable on the same body through the exhaust-mechanism option code "N" (example part number AR30-F03BE-N-D). A made-to-order variant (suffix -X406) offers a reduced 0.05 to 0.4 MPa set range. For tighter regulation accuracy than the general-purpose AR-D delivers, SMC's separate IR precision-regulator series is used instead.
Why SMC here SMC is the spec'd-in benchmark; the AR-D matches an SMC-based machine, and the IR precision line gives a clear in-brand path when an application needs tighter regulation than a general-purpose regulator delivers.
ZP / ZP2 / ZP3 series suction cups
Coverage Three families: ZP (general-purpose legacy line), ZP2 (broad general-purpose, 2-340 mm), ZP3 (compact, shortened buffer body). Cup design is chosen within the family — ZP2 publishes four core designs (flat, flat-with-rib, deep, bellows) plus special variations (miniature, compact, nozzle, multi-bellows, sponge, mark-free, oval, heavy-duty); design is selected by surface geometry. Materials: ZP2 lists six pad materials covering NBR (oily/general industrial), silicone (high-temp/food), urethane (abrasive high-cycle), FKM/fluorosilicone (chemical/semiconductor), plus conductive/anti-static and mark-free compounds. Buffer stroke: up to 100 mm (ZP2) or up to 20 mm (ZP3). [VERIFY] the SMC USA product page does not enumerate ZP-vs-ZP3 diameter ranges or the exact six ZP2 material codes — confirm against the full SMC vacuum-pad catalog before publishing per-style material tables.
SMC's suction-cup line spans three families covering one of the widest style-and-material ranges in the market. ZP2 is the broad general-purpose family — diameters from 2 to 340 mm, built around four core cup designs (flat, flat with ribs, deep, and bellows) in six pad materials, plus a large set of special variations: miniature, compact, nozzle, multi-bellows, sponge, mark-free, oval, and heavy-duty cups. ZP3 is the compact family, built on a compact pad with a shortened buffer body for tight end-of-arm tooling, with optional buffers up to 20 mm stroke. The older ZP series remains available as a complete general-purpose line for small-diameter and legacy needs. Cup design is a sub-option selected within each family rather than a separate series code; ZP2 buffers offer up to 100 mm stroke versus up to 20 mm on ZP3.
Why SMC here SMC ZP cups carry published grip-force and dimensional data, so a cup can be sized to the workpiece instead of guessed — and they share the SMC vacuum-circuit fittings already on the machine. The breadth of styles and materials means one brand covers the cardboard, glass, food, and abrasive-metal jobs a DC customer sees across a plant.
ZH series body-ported single-stage vacuum ejectors; ZL112 / ZL212 series three-stage multistage ejectors
Coverage Single-stage = ZH series. Multistage = ZL series, three-stage diffuser construction: ZL112 (1.2 mm nozzle, 100 L/min suction flow) and ZL212 (2 x 1.2 mm nozzle, 200 L/min suction flow, ~2x the ZL112). The multi-stage recommendation boundary: specify ZL whenever the application is porous/leaky workpieces or needs high suction flow rather than high vacuum; within ZL, ZL112 is the entry/compact choice and ZL212 the high-flow choice. Both ZL models: -84 kPa max vacuum, 0.2-0.5 MPa supply. Exhaust: built-in silencer (Nil) or port exhaust (P). Vacuum sensing option: none, vacuum port adaptor Rc 1/8 (GN), vacuum pressure gauge (G), or digital pressure switch for vacuum (D) — the D option fits an embedded ZSE30A-equivalent switch. Valve options: K1 (supply + release valves) or K2 (supply valve only); the vacuum switch is not separately replaceable — the whole suction cover assembly is ordered (part-number scheme ZL-SC[size]). [VERIFY] ZH single-stage model details (nozzle bores, mounting styles) are not in the supplied ZL datasheet — confirm against the SMC ZH catalog before publishing ZH specifics.
SMC's ejector range splits by stage count. The ZH series is the compact single-stage body-ported ejector — built-in exhaust silencer, a check valve on the vacuum port to hold vacuum when supply is off, and one-touch or screw-in port connections. For porous surfaces and high suction-flow demand, the ZL series multistage ejectors stack three diffuser stages: ZL112 has a single 1.2 mm nozzle (100 L/min max suction flow, 63 L/min air consumption, -84 kPa max vacuum), and ZL212 doubles the nozzles (2 x 1.2 mm) for 200 L/min suction flow at 126 L/min air consumption — roughly twice the flow of the ZL112 and a 250% suction-flow increase over a comparable single-stage nozzle at about 20% lower air consumption. Both ZL run a 0.2-0.5 MPa supply (0.4 MPa standard), 0.7 MPa max. ZL units are configurable with built-in silencer or port exhaust, vacuum pressure gauge or built-in ZSE30A digital vacuum switch, and supply/release valve options (ZL112: One-touch fittings and SYJ514 valves; ZL212: larger Rc 3/4 vacuum port, SYJ714 valves).
Why SMC here SMC is the global pneumatics benchmark and the brand SPC's pneumatic-automation customers most often already run. When a machine is built on SMC cylinders and valves, the ZH/ZL ejector drops onto the same manifold, tubing, and fitting standards — one vendor and one catalog for the whole vacuum circuit, with documented flow-vs-vacuum performance curves for correct sizing.
ZSE20(F) / ZSE20A(F) / ZSE20B(F) / ZSE20C(F)-(H) 3-screen digital pressure switches; ZSE20B(F)-L / ZSE20C(F)-L IO-Link models; ZSE30A compact digital switch (ISE equivalents on positive pressure)
Coverage Current ZSE20 catalog tiers: ZSE20(F) IP40 / 1 output; ZSE20A(F) IP40 / 2 outputs (Copy + Auto-shift, optional analog); ZSE20B(F) IP65 / 2 outputs (analog); ZSE20C(F)/C(H) IP65 / 2 outputs, general fluids, withstand to 4 MPa. Range: (F)-suffix models are compound (vacuum + low positive); non-F are vacuum-only (rated to -101 kPa) or positive-only on the ISE equivalents. IO-Link: only ZSE20B(F)-L and ZSE20C(F)-L — IP65, IO-Link 1.1, 1 output in SIO mode, 16-bit process data; standard non-L models are not networked. Copy/Auto-shift and several made-to-order options are not available on the -L IO-Link types. Outputs: NPN or PNP open-collector, 1 or 2 outputs, optional analog voltage/current. ZSE30A is a separate compact 2-color-display switch (NPN/PNP, optional analog), the embedded switch on ZL ejectors.
SMC's vacuum-switch line is the ZSE family (ISE on positive-pressure equivalents). Within the current 3-screen high-precision ZSE20 catalog the line is tiered by output count and enclosure: ZSE20(F) is the IP40 1-output base model; ZSE20A(F) is the IP40 2-output model and adds Copy and Auto-shift functions plus optional analog output; ZSE20B(F) is the IP65 2-output sealed model with analog output; ZSE20C(F)/ZSE20C(H) is the IP65 2-output model for general fluids (withstand pressure up to 4 MPa). The (F) suffix denotes the compound range — vacuum plus low positive pressure — versus vacuum-only on the base ZSE20. IO-Link is carried only on the -L models: ZSE20B(F)-L and ZSE20C(F)-L (IP65, IO-Link 1.1, 1 output in SIO mode); the IO-Link version carries 16-bit process data and a block-parameter / data-storage function. The separate ZSE30A series is a compact 2-color-display digital switch (NPN/PNP open-collector, optional analog) used as the integral switch on SMC's ZL multistage ejectors. Port options include M5, Rc/NPT 1/8, and one-touch tube fittings.
Why SMC here When the vacuum circuit and the machine's valves are SMC, a ZSE switch reports onto the same IO-Link network as the EX-series valve terminal — vacuum grip status, valve position, and sensor data all on one network, no separate gateway. For SPC's automation customers it keeps part-present verification inside the brand the machine already runs.
SMC valve repair via individual replacement spare parts catalogued per valve series (SY, VQ and related directional-control-valve lines) — no discrete SMC valve seal-kit product line
Coverage SMC supplies valve repair on a spare-parts basis — individual seals, gaskets, and sub-plate components catalogued per valve series — not as packaged seal kits selected by valve type. There are no SY-series, VQ-series, or other SMC valve seal-kit part numbers to enumerate. The repair part is identified from the valve model number via SMC's maintenance-parts list and seal-kit search tool.
SMC has confirmed directly (vendor reply, 2026-05-22) that it generally does NOT make rebuild kits for valves. SMC repairs a worn directional control valve by supplying individual replacement spare parts — sub-plates, gaskets, individual seals and similar components listed in each valve catalog — rather than a single packaged valve seal-kit part number. This is the opposite of SMC's cylinder line, where a discrete bore-specific seal kit (CQ2B-PS and similar) is published. The earlier draft's claim of "SY-series seal sets keyed to series/function/body size" is not supported and is withdrawn — no SY-series seal-kit part number could be confirmed from any SMC source.
Why SMC here When the installed valve is SMC, SMC's own replacement parts are the exact-match repair — the individual seals and service components are engineered to the SY-series spool and seat geometry, so a rebuild restores the valve to its original sealing performance. SMC's maintenance-parts catalog and online seal-kit search tool identify the right parts from the valve nameplate.
