The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX225-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 225mm 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 SAIJ32X225-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 225 mm stroke that can be fine-tuned backward by up to 30 mm, yielding a usable travel window of 195 to 225 mm.
This variant uses a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. It features PT tapered port threads (G1/8) and lacks a magnet, meaning it is not equipped for position sensing out of the box. The extruded aluminum barrel includes sensor grooves on both sides should you later need to add sensing capabilities.

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 195 to 225 mm end-stop during product size changes on a packaging line without replacing the cylinder.
Fine-tune the retract position during machine commissioning to perfect the pressing distance of delicate components.
Adjust the travel window on the fly for prototype testing equipment where the optimal stroke length is still being determined.
Select this 32 mm bore adjustable cylinder when your assembly requires precise end-position tuning during commissioning without swapping out physical hardware. The rear adjuster acts strictly as a mechanical stop to set the travel end; it does not hold the load without live air pressure. For true load-holding requirements, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 225 mm nominal stroke, 30 mm adjustment range, PT G1/8 ports, and standard mounting interface. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR brackets. Since this model features a 225 mm stroke, ensure proper external guidance to prevent excessive side-loading on the piston rod.
Quick checklist
At the maximum pressure of 1.0 MPa, it can deliver up to 82 kgf.
A rear external screw acts as a mechanical stopper, allowing you to shorten the effective stroke from 225 mm down to as little as 195 mm. This adjuster only sets the travel end and deceleration; it does not lock or hold the load without continuous air pressure.
