The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX220-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 220mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ32X220-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated rear stopper allows you to trim the nominal 220mm stroke back by up to 40mm, providing a precise 180 to 220mm usable travel window for exact end-position tuning.
This SKU includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet for position sensing. It pairs seamlessly with AirTAC CMSE reed and DMSE solid-state switches via the dual-side sensor grooves on the extruded aluminum barrel. The adjuster acts purely as a mechanical stop to fine-tune the retract position without needing external stops, but it will not hold a load without live air pressure.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Dial the stroke back by up to 40mm to adapt the retract end-position for different product sizes without swapping out the entire cylinder.
Fine-tune the 180-220mm travel window during initial machine setup to absorb mechanical tolerances and achieve precise positioning.
Leverage the SUS304 stainless steel rod and adjustable stroke for precise actuation tasks in packaging or food processing lines.
The rear adjuster screw lets you dial in the travel window from 180 to 220mm, preventing the need to swap cylinders for minor length differences.
For load-holding without continuous air supply, remember that this cylinder's rear stopper and air cushions function only as travel deceleration, not as a lock; you should look at the SAIL or BSAI series instead. To match this exact ISO 15552 replacement, specify a 32mm bore, 220mm stroke, 40mm adjustment range, PT tapered port threads, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
It operates at speeds between 30 and 800mm/s and features a 27mm cushion length at both ends.
The rear adjuster screw mechanically stops the piston, allowing you to shorten the 220mm nominal stroke by up to 40mm. This creates a 180 to 220mm usable travel window for fine-tuning without adding external stops.
