The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX500-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 500mm 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 SAIJ32X500-75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 425-500mm usable travel window, letting you dial back the 500mm nominal stroke by up to 75mm during commissioning.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE electronic solid-state switches if a magnet is added later. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1 and TCM2.

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.

Quickly fine-tune the 425-500mm travel window during product size changes without replacing the cylinder or adding external mechanical stops.
Ideal for automated test fixtures where the exact retract distance needs precise dialing-in at commissioning via the rear stopper screw.
If you need greater thrust, stepping up to the 40mm bore yields 628N. The 75mm adjustment window is ideal for product changeovers, allowing you to fine-tune the retract end-position without swapping the cylinder or bolting on external stops.
Because the 500mm stroke is long relative to the 12mm rod diameter, an external guide is recommended to prevent excessive side-loading. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an external rod lock or the AirTAC SAIL or BSAI series. For a direct ISO 15552 replacement, match the 32mm bore, 500mm stroke, 75mm adjustment, PT ports, and the specified mounting style.
Quick checklist
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the effective travel from the 500mm nominal stroke down to 425mm. It acts as a mechanical stop to fine-tune the end position and works alongside the standard air cushions, but it does not lock or hold the load without continuous air pressure.
