The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-20S 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 a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ160X325-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end-position during commissioning. It provides a usable travel window of 305-325 mm, allowing precise variable end-stops without adding external stops. It features a SUS304 stainless steel rod and an integrated magnet for position sensing.
Delivering 10053 N of pull force at 0.5 MPa (up to 18095 N push at 0.9 MPa), this 160 mm bore profile cylinder handles heavy loads. It uses PT tapered ports (G3/4) and includes variable air cushions at both ends. The rear adjuster acts as a travel stop, not a lock, so live air is required to hold the load.

Dial in the exact 305-325 mm retract position on heavy pressing machinery during commissioning without machining external stop collars.
Quickly adjust the end-stop by up to 20 mm on automated lines when switching product sizes, reducing machine downtime.
Leverage the 18095 N push force and variable air cushions to decelerate heavy metal or composite forming loads smoothly.
Choose this adjustable-stroke model when your machine setup requires exact end-position tuning or frequent product-size changeovers without swapping cylinders. If you need less force, the 125 mm bore yields 5734 N of pull at 0.5 MPa. For load-holding without live air pressure, use an SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead of relying on the adjuster.
To match this ISO 15552 cylinder, specify a 160 mm bore, 325 mm stroke, 20 mm adjustment, PT G3/4 ports, and a magnet for CMSE or DMSE sensors. Because the stroke is 325 mm, the 40 mm SUS304 rod and M36x2 thread carry high side-load capacity, but long unsupported travel still requires an external guide. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
At 0.5 MPa it provides 10053 N of pull force and 14074 N of push force. At 0.9 MPa, the push force reaches 18095 N.
A rear stopper screw lets you trim the effective travel back by up to 20 mm, creating a 305-325 mm usable window. It acts as a travel stop, not a lock, so the cylinder needs live air to hold position.
