The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX750-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 750mm 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 SAIJ32X750-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 730-750mm usable travel window, allowing you to dial in the exact end position during commissioning without adding external stops.
This unit uses a SUS420J2 stainless steel rod for improved corrosion resistance over standard carbon steel. It includes adjustable air cushions at both ends to decelerate the load, but note 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 730-750mm retract distance precisely during machine setup to accommodate varying material lengths without changing hardware.
Quickly adjust the stroke end position by up to 20mm when switching the line to a new product size, minimizing downtime.
Achieve exact end-position alignment at commissioning using the rear screw, avoiding the need to bolt on physical spacers.
The 20mm adjustment range is perfect for product changeovers on a line, letting you fine-tune the retract position rather than swapping a fixed-stroke SAI cylinder. For direct replacement, match the 32mm bore, 750mm stroke, PT tapered ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
Because the stroke is 750mm, the 12mm rod and M10x1.25 thread need external guidance to prevent side-load damage over this long unsupported travel. For any load-holding requirements without live air, use an external rod lock or pilot-operated check valve, as the adjuster here is not a brake.
Quick checklist
At the maximum operating pressure of 1.0 MPa, it delivers up to 80kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 750mm down to 730mm, giving a 730-750mm usable window. It acts as a mechanical stop to fine-tune the end position and does not lock the load.
