The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX225-75 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 SAIJ32X225-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 150 to 225 mm, allowing you to dial back the 225 mm nominal stroke by up to 75 mm during commissioning.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic sensors if a magnet is specified later. It supports a speed range of 30-800 mm/s.

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 150-225 mm travel window during product size changes to set new end positions rapidly without mechanical rebuilds.
Use the 75 mm rear screw to adjust the retract position on the fly for sorting or diverting items of varying lengths.
Fine-tune the final retract position during machine setup to perfect alignment without fabricating custom external spacers.
If your process needs higher force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. The 75 mm adjustment range is ideal for product changeovers, letting you fine-tune end positions without adding external stops or swapping the cylinder.
For load-holding without live air pressure, note that this SAIJ adjuster acts only as a travel stop, not a lock; you would need an SAIL or BSAI series cylinder instead. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The 12 mm rod and M10x1.25 thread handle moderate side loads, but long unsupported strokes still require an external guide.
Quick checklist
The operational speed range for this 32 mm bore is 30-800 mm/s.
The rear adjuster screw lets you shorten the 225 mm nominal stroke by up to 75 mm, giving a usable travel window of 150 to 225 mm. It acts as a mechanical stop to tune the end position and is not a lock to hold loads without air pressure.
