The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX230-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 230mm 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 SAIJ32X230-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 230 mm nominal stroke that can be dialed back by up to 50 mm, creating a precise 180-230 mm usable travel window for product changeovers.
This variant includes an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and carries a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the rear stopper allows mechanical end-position tuning without adding external stops.

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 180-230 mm travel window during format changes without physically swapping cylinders or adding external mechanical stops.
Fine-tune the retract stroke by up to 50 mm at commissioning to perfect the resting position of delicate tooling.
Leverage the built-in magnet for CMSE or DMSE switches to confirm the adjusted end position in automated control systems.
The adjustable 180-230 mm window is ideal for machines running multiple product sizes, letting you fine-tune the retract end at commissioning rather than swapping a fixed-stroke SAI cylinder. Because the 230 mm stroke exceeds 300 mm? No, but for any extended stroke, ensure external guides support the load to prevent rod binding.
For ISO 15552 replacement matching, specify bore 32, stroke 230, adjustment 50, PT tapered port thread, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for positive load-holding without pressure, consider an external rod lock or the SAIL/BSAI series. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
Quick checklist
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from its 230 mm nominal length down to 180 mm. It only sets the travel end and does not lock the load without live air pressure.
