The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX475-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 475mm 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 SAIJ32X475-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 425 to 475 mm, enabling precise end-position tuning during commissioning without swapping out the unit. The extruded aluminum barrel includes sensor grooves on both sides.
Because the stroke extends to 475 mm on a 12 mm rod, an external guide is recommended to prevent excessive side-loading. This model includes a magnet for position sensing and uses PT tapered ports. The rear adjuster acts purely as a mechanical stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

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 425-475 mm travel window during product size changes to set new end positions rapidly without mechanical rework.
Fine-tune the retract stop during commissioning to perfect the mating distance of delicate components on the line.
Adjust the stroke on the fly for packaging lines that handle varying package lengths within the 50 mm adjustment range.
Choose this 32 mm bore unit when an application requires exact end-stop calibration over a 425-475 mm range, avoiding the need for fixed external stops. The rear screw allows quick product changeovers on a line, but remember it is a stop, not a lock. To match this ISO 15552 replacement exactly, verify the 475 mm stroke, 50 mm adjustment, PT port thread, and the -S magnet for CMSE or DMSE sensors.
Given the 475 mm stroke, the 12 mm rod requires external support to manage side loads and prevent binding over long travels.
Quick checklist
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 50 mm, creating a usable travel window of 425 to 475 mm. This mechanical stop sets the end position but does not lock or hold the load without continuous air pressure.
