The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX150-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 150mm 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.
It features a SUS304 stainless steel rod and a PT tapered port thread. The built-in magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors.
With a 150 mm nominal stroke and a 10 mm adjustment range, this model provides a usable travel window of 140 to 150 mm. This allows you to fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable air cushions at both ends help manage the kinetic energy of heavy loads.

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 140 to 150 mm end-stop during initial machine commissioning to accommodate material thickness variations without external shims.
Quickly adjust the retract position on a packaging line when switching between different product sizes, leveraging the 10 mm trim window.
The adjustable stroke is ideal for machine setups requiring exact end-position tuning during product changeovers. Because the stroke is 150 mm, the robust 40 mm rod handles side loads well, though any long unsupported travel still requires an external guide.
For an exact ISO 15552 replacement match, specify a 160 mm bore, 150 mm stroke, 10 mm adjustment, PT ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without live air pressure. For true load-holding, consider the SAIL or BSAI series. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 140 to 150 mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
