The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX750-30 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 SAIJ32X750-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 750mm travel but integrates an external stopper screw that allows you to fine-tune the effective stroke backward by up to 30mm, creating a 720-750mm usable positioning window. This built-in adjustability is ideal for dialing in exact end positions during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and dual-side sensor grooves on the extruded aluminum barrel. Note that the rear adjuster acts strictly as a travel stop to set deceleration and end-position, not as a locking device; it will not hold a load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead.

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 720-750mm window during machine commissioning without installing external physical stops.
Quickly adapt the cylinder's effective stroke on a packaging line when handling different product sizes or formats.
Utilize the full 750mm travel for automated assembly processes while retaining the ability to trim the stroke by up to 30mm for precise tooling alignment.
The adjustable stroke is highly advantageous for product changeovers on a line, allowing you to shift the end-stop without physically swapping the cylinder. When replacing an ISO 15552 cylinder, match the 32mm bore, 750mm stroke, 30mm adjustment, PT port thread, and standard mounting interface.
Because the 750mm stroke is relatively long for a 32mm bore, the 12mm diameter piston rod is susceptible to side-loading and sagging. You must use an external guide to support the load and prevent rod binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts found on some other series.
Quick checklist
At 0.7 MPa, the push force increases to 563N. The standard operating speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 750mm down to 720mm. This creates a 720-750mm adjustable travel window. The adjuster only sets the travel end and deceleration point; it does not lock or hold the load without continuous air pressure.
