The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX325-30S 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-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 295 to 325 mm usable travel window for precise end-position tuning. This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
Because the 325 mm stroke exceeds typical unsupported lengths, the 40 mm rod diameter and M36x2 thread require an external guide to manage side loads. The rear adjuster acts strictly as a travel stop to dial in the retract position without swapping the cylinder, but it does not hold the load without live air pressure.

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 295-325 mm retract position during product size transitions without replacing the cylinder or bolting on external stops.
Leverage 18095 N of pull force to seat heavy components, using the rear stopper to fine-tune the final clamping position at commissioning.
Adjust the effective travel window on automated assembly lines to accommodate varying part dimensions on the fly.
An adjustable stroke is selected over a fixed SAI cylinder when a machine requires fine end-position tuning during commissioning or product changeover without adding external stops.
For ISO 15552 interchangeability, match the 160 mm bore, 325 mm stroke, 30 mm adjustment, PT G3/4 port, and -S magnet. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster and air cushions only decelerate the travel end; they do not lock the load. For true position holding without live air, use an external rod lock or pilot-operated check valve.
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 to 325 mm usable travel window. It sets the retract end position but does not lock the load without live air pressure.
