The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX50-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 50mm 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.
Because the 50mm adjustment code matches the nominal stroke, you can dial the effective travel down to a zero-stop, providing a 0-50mm usable window for highly precise positioning. This flexibility eliminates the need to physically swap cylinders during product changeovers.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 32mm bore unit features PT tapered ports and a 12mm rod with an M10x1.25 thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic sensors exactly where needed without external brackets.

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 from 0 to 50mm during format changes without physically replacing the cylinder or adding shims.
Fine-tune the final resting position at machine commissioning to perfectly mate with varying part geometries.
Set multiple retract endpoints on a single axis to handle different product sizes on the same conveyor line.
If your setup needs less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore yields 628N. The rear adjuster acts strictly as a mechanical stop for the retract stroke and does not lock the load; for true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. This SAIJ variant uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.
Quick checklist
The rear adjuster screw lets you shorten the effective stroke by up to 50mm. Since the nominal stroke is 50mm, the usable travel window is 0-50mm, allowing you to set the exact retract end-position without changing the cylinder.
