The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX145-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 145mm 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.
Its defining trait is a massive 100mm adjustment range, creating a usable travel window of 45-145mm. This allows operators to dial in the exact end position during commissioning without swapping hardware or adding external stops.
Built with a SUS304 stainless steel rod (option B), this model handles environments where standard carbon steel would corrode. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic sensors, fitting neatly into the dual-side sensor grooves of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop for deceleration, meaning it will not hold a load without continuous 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 in the precise retract distance between 45 and 145mm during machine setup, perfect for testing different actuation depths on the fly.
Quickly adapt packaging lines to new container sizes by turning the rear adjuster, avoiding the need to physically swap out the entire cylinder.
Leverage the SUS304 stainless steel rod for light-duty pushing tasks in washdown or mildly corrosive manufacturing environments.
Choose this 32mm bore when an application demands extreme flexibility in end-position tuning, offering a 45-145mm window that far exceeds standard trim ranges. For load-holding without live air, a plain SAIJ is insufficient; you would need to specify a SAIL pneumatic lock or an external rod lock.
To match this exact ISO 15552 footprint for a direct replacement, confirm the 32mm bore, 145mm nominal stroke, 100mm adjustment code, PT tapered port threads, and the -S magnet. Because the nominal stroke is 145mm, side-load risks are minimal, but always ensure the M10x1.25 rod thread is aligned correctly to avoid binding.
Quick checklist
If operated at 0.7 MPa, the push force increases to 563N.
The rear adjuster allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 45-145mm, letting you fine-tune the end position without changing the cylinder's physical mounting.
