The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX900-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 900mm 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 SAIJ32X900-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 850 to 900 mm, enabling precise end-position tuning without external stops.
This unit includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. Adjustable air cushions at both ends manage deceleration over the long stroke.

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.

Quickly adapt the end-stop for different product lengths on a packaging line using the 50 mm adjustment screw.
Fine-tune the travel end to meet varying process requirements while relying on standard ISO 15552 dimensions.
Choose this adjustable-stroke model over a fixed SAI when you need variable end-stops for machine setup or product changeovers. Because the 900 mm stroke is long, an external guide is recommended to manage side loads despite the 12 mm rod diameter. The rear adjuster acts strictly as a travel stop, not a lock; the cylinder will not hold its load without live air pressure. For load-holding without continuous pressure, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
The rear adjuster allows you to shorten the effective travel from the nominal 900 mm down to 850 mm. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
