The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX65-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 65mm 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 SAIJ100X65-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 25-65 mm usable travel window, allowing you to dial back the 65 mm nominal stroke by up to 40 mm during commissioning. The 100 mm bore delivers substantial thrust, pushing 5497 N and pulling 3681 N at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This variant includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and a magnet for position sensing. It accepts AirTAC CMSE reed and DMSE solid-state switches in the dual-side sensor grooves. The PT tapered port thread and integrated adjustable air cushions at both ends ensure reliable sealing and smooth end-of-stroke deceleration.

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.

Fine-tune the pressing depth of heavy-duty assembly stations by up to 40 mm on the fly, accommodating different material thicknesses without swapping out the entire cylinder.
Rapidly adjust the retract end-position during product size changeovers on a packaging line, using the rear stopper to set precise 25 to 65 mm travel limits.
Choose this 100 mm bore cylinder when an application requires high force combined with variable end-stop positioning, such as tuning a press or clamp distance without adding external mechanical stops. The rear adjuster acts solely as a travel stop and cannot hold a load without live air pressure; for true fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 65 mm stroke, 40 mm adjustment range, PT G1/2 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets. Since the 65 mm stroke is relatively short, side-load stress is minimal, but an external guide is still recommended for heavy offset loads.
Quick checklist
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 65 mm nominal stroke by up to 40 mm, providing a usable travel window of 25 to 65 mm. It functions as a travel stop and does not lock the load without continuous air pressure.
