The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 375mm 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 SAIJ32X375-100 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. By incorporating a 100 mm adjustment range, this model allows you to dial back the 375 mm nominal stroke, creating a highly flexible 275 to 375 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position detection.
Equipped with PT tapered G1/8 ports and a 12 mm rod with an M10x1.25 thread, this cylinder achieves standard speeds between 30 and 800 mm/s. The rear stopper mechanism enables precise end-position tuning during commissioning without adding bulky external stops. It is important to note that this adjuster acts purely as a travel stop and does not hold the 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 in the exact 275 to 375 mm travel distance during machine setup to accommodate varying product lengths without swapping out the entire actuator.
Rapidly adjust the rear stopper on the production line to fine-tune end positions when switching between different product sizes or tooling configurations.
Choose this 32 mm bore adjustable-stroke cylinder when your application requires variable end-stops for rapid machine changeover or product-size adjustments, rather than a fixed-stroke SAI model. Because the 375 mm stroke creates a long unsupported rod extension, an external guide rail is strongly recommended to prevent excessive side-loading and premature wear.
For load-holding applications without continuous air pressure, this cylinder's adjuster and air cushions will not act as a brake. In those scenarios, you should specify an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder instead. To replace an existing ISO 15552 unit, match the 32 mm bore, 375 mm nominal stroke, 100 mm adjustment code, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Quick checklist
It operates at a standard speed range of 30 to 800 mm/s, driven by its G1/8 PT port and 12 mm diameter rod.
The rear adjuster acts as a mechanical stop that lets you shorten the 375 mm nominal stroke by up to 100 mm, providing a usable travel window of 275 to 375 mm. It functions as a travel stop for end-position tuning and does not lock or hold the load without live air pressure.
