The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX125-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 125mm 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 SAIJ32X125-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 95 to 125 mm usable travel window, allowing you to dial back the 125 mm nominal stroke by up to 30 mm during commissioning.
This adjustable model omits the FB, CA, CB, and CR mounts, offering a focused set of interfaces: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet enables precise tracking via CMSE reed or DMSE electronic sensors fitted into the dual-side barrel grooves. The PT tapered port ensures a tight, sealed pneumatic connection.

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.

Quickly adjust the end-stop from 95 to 125 mm to accommodate varying package sizes on a packaging line without swapping hardware.
Fine-tune the retract position during initial commissioning to align sensors and tooling perfectly, eliminating mechanical guesswork.
Set precise travel limits for light-duty pressing or positioning tasks where hitting a specific 95-125 mm window is critical.
If your process requires less force, stepping down is not an option in this series, but if you need higher force, the 40 mm bore provides 628 N. The rear adjuster acts purely as a mechanical stop for deceleration and positioning; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead.
This dimensionally interchangeable ISO 15552 cylinder uses a PT port and features a 12 mm rod with an M10x1.25 thread. Because the stroke is 125 mm, side-load risks are minimal, but always ensure the rod thread properly handles any lateral forces. It provides a direct replacement for standard ISO 15552 cylinders while adding crucial adjustability.
Quick checklist
The rear adjuster screw lets you shorten the effective travel from the 125 mm nominal stroke down to 95 mm, providing a 30 mm tuning window. It acts as a physical stop to set the end position and does not lock the load without continuous air pressure.
