The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX280-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 280mm 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 SAIJ32X280-100-S is a double-acting, adjustable-stroke ISO 15552 profile cylinder featuring a 32mm bore and a 280mm nominal stroke. An integrated rear stopper mechanism allows you to dial back the travel by up to 100mm, creating a highly flexible 180-280mm usable window for precise end-position tuning during commissioning.
This specific SKU is configured with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a built-in magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. Unlike fixed-stroke SAI units, this model lets you fine-tune the retract position on the fly. Remember that the rear adjuster acts only 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 retract distance within the 180-280mm window during machine commissioning to accommodate different product sizes without changing cylinders.
Rapidly adjust the stroke stopper on packaging lines when switching between different package lengths, minimizing downtime.
Leverage the built-in magnet with DMSE electronic sensors to confirm the adjusted end-of-stroke position in high-precision assembly tasks.
Choose this 32mm bore adjustable cylinder when your machine setup requires variable end-stops or frequent product changeovers, eliminating the need to bolt on external stops or swap the entire cylinder. The PT tapered port and M10x1.25 rod thread suit standard pneumatic setups, though the 280mm stroke warrants an external guide to prevent excessive side-loading on the rod.
For dimensionally interchangeable ISO 15552 replacements, match the 32mm bore, 280mm stroke, -100mm adjust code, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR. Because the rear adjuster and air cushions only decelerate the stroke, they do not function as a lock; for load-holding without live air, select the SAIL or BSAI series instead.
Quick checklist
The rear adjuster screw lets you shorten the 280mm nominal stroke by up to 100mm, providing a usable travel range of 180-280mm. The adjuster acts as a physical stop to fine-tune the end position but does not lock the load without continuous air pressure.
