The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX325-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 325mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ160X325-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 295 to 325 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Because the rear adjuster acts purely as a mechanical stop to fine-tune end positions, it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. This SAIJ model supports a speed range of 30-500 mm/s and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 295-325 mm travel end position during machine setup to apply consistent 14074 N clamping force without external stops.
Quickly adjust the rear stopper to accommodate new product sizes on the line, reducing downtime and eliminating the need to swap cylinders.
Fine-tune the end-of-stroke position during commissioning to ensure precise alignment of heavy components without mechanical shims.
An adjustable stroke is ideal for product changeover, allowing you to dial in the exact end position without swapping cylinders or adding external stops. At 325 mm of travel, the 40 mm rod diameter handles significant loads, but long unsupported strokes require an external guide to prevent side-load wear. To replace an ISO 15552 cylinder, match the 160 mm bore, 325 mm stroke, 30 mm adjustment, PT ports, and the chosen mounting.
Quick checklist
The rear adjuster acts as a mechanical stop that lets you shorten the 325 mm nominal stroke by up to 30 mm, creating a 295-325 mm usable travel window. It only sets the end position and does not lock the load without live air.
