The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 75mm 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 SAIJ32X75-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel anywhere within a 0 to 75 mm window. This extreme adjustability is ideal for machine setups requiring highly variable end-stops without swapping hardware. It features a SUS420J2 stainless steel rod and a built-in magnet for CMSE reed and DMSE electronic sensors.
The rear adjustment screw acts purely as a mechanical stop to set the retract position; it does not lock or hold the load without live air pressure. For position-holding needs, an external rod lock or AirTAC SAIL series is required.

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 retract position from 0 to 75 mm during machine commissioning to accommodate different product sizes without changing the cylinder.
Rapidly adjust the travel limit on packaging lines when switching between part configurations, using the rear stopper instead of adding external mechanical stops.
The PT tapered port is G1/8, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.
Because the nominal stroke is under 300 mm, side-load stress on the 12 mm rod is manageable without an external guide, though long unsupported strokes still require one. To replace an ISO 15552 cylinder, match the 32 mm bore, 75 mm stroke, 75 mm adjustment, PT G1/8 port, and the -S magnet requirement.
Quick checklist
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 0 to 75 mm. It only sets the end position and does not hold the load without live air pressure.
