The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX325-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 325mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ100X325-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 325 mm nominal stroke that can be fine-tuned down by 10 mm, yielding a 315-325 mm usable travel window for precise end-position calibration during commissioning.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the stroke exceeds 300 mm, an external guide is recommended to prevent excessive side-loading on the extended rod.

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 exact 315-325 mm travel window during machine commissioning to perfect part ejection without physically swapping the actuator.
Quickly adjust the retract end-position by up to 10 mm on automated lines handling slightly varying product lengths.
The 10 mm rear adjuster allows you to dial in the exact end-stop without swapping cylinders or adding external stops, making it ideal for product changeovers. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series.
To replace an existing ISO 15552 cylinder, match the 100 mm bore, 325 mm stroke, 10 mm adjustment range, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2; omitting FB, CA, CB, CR). As this configuration omits the -S magnet, it does not support AirTAC CMSE or DMSE sensors.
Quick checklist
At the maximum 1.0 MPa pressure, the push force reaches 801 kgf.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 10 mm, creating a 315-325 mm usable travel window. It is a travel stop only, not a lock, and cannot hold the load without continuous air pressure.
