Adjustable Tunable orifice · longest life on fixed-load duty
Fixed load, fixed cycle, longest service life.Dedicated production lines, indexing tables, high-cycle transfer stations — anywhere the load mass and impact velocity stay the same cycle after cycle. SMC RB and KOBA adjustable platforms cover the standard energy capacities; tuning the orifice to the exact duty extends service life dramatically over a self-compensating shock on the same job.
Needs commissioning + re-tune on part changeThe advantage disappears the minute the part mix changes — every new load mass or cycle speed needs the orifice re-tuned, and a mis-tuned adjustable shock decelerates worse than a properly-sized self-compensating one. Don't quote adjustable for job-shop or variable-mix production; the operator won't re-tune.

Self-Compensating Auto-tuning across load range · no commissioning
Variable load, job-shop, no operator tuning.Job-shop production, custom fabrication, automated cells running a mix of part weights and speeds. SMC RJ and KOBA self-compensating platforms auto-adjust the orifice across the load envelope — "drop it in and it works" decelerates whatever comes through.
Shorter service life per cycle · narrower energy bandThe auto-tuning compromise gives up 30-50% of cycle life versus a correctly-tuned adjustable on the same duty, and the rated energy band is narrower per size. Trade-off is worth it when re-tuning isn't realistic; not worth it on a dedicated high-volume line where adjustable wins on TCO.

Reading the brand bench column — the bar shows how many of SPC's tier slots (Industry Leader · Emerging · Economical · adjacent) carry an option at that product type. A deep bench means a price-driven and a spec-driven option both close cleanly; a narrow bench means the available brands map closely to the technical requirements and the comparison stops being a tier choice.
