The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX140-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 140mm 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 SAIJ32X140-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 110 to 140 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
This specific SKU uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw acts as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device; the cylinder relies on live air to hold a load.

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 110-140 mm travel window during product size transitions to set new retract endpoints without swapping the cylinder.
Fine-tune the final retract position at machine commissioning to clear mechanical interference using the built-in rear stopper.
The 12 mm rod and M10x1.25 thread provide a compact interface, but for this 140 mm stroke, ensure external guides are used if side loads are present. To match this ISO 15552 interchangeable replacement, specify a 32 mm bore, 140 mm stroke, 30 mm adjustment, PT ports, SUS304 rod, and no magnet.
If load holding without live air pressure is required, the rear adjuster will not function as a brake; consider the SAIL pneumatic lock series or an external rod lock instead. Available mountings for this profile cylinder include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the nominal 140 mm stroke by up to 30 mm, creating a usable travel window of 110 to 140 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
