The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 100mm 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.
Its 100mm nominal stroke can be dialed back by up to 75mm, creating a highly versatile 25-100mm usable travel window for precise end-position tuning during commissioning. This extreme adjustment range allows a single cylinder to cover multiple product sizes without swapping bodies.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 32mm bore unit features PT tapered ports and a 12mm rod thread. It shares the standard extruded aluminum barrel with sensor grooves on both sides, though it omits the FB, CA, CB, and CR mounting options found on some variants, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces instead.

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.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Leverage the 25-100mm travel window to dial in the exact retract position on the fly, perfect for prototyping and short-run changeovers.
Adjust the stroke to match different package sizes on a single conveyor line without physically replacing the actuator or adding external stops.
Utilize the SUS304 stainless steel rod in light chemical or washdown settings where standard carbon steel rods would fail prematurely.
If your setup needs less force, stepping down is not an option within the SAIJ range, but if you require higher thrust, the 40mm bore provides 628N at 0.5MPa. The 75mm adjustment range is ideal for machines running multiple product sizes, acting as a variable end-stop that replaces fixed SAI cylinders.
Because this is a double-acting cylinder, the rear adjuster and air cushions only decelerate the travel end; they do not hold the load without live air. For dead-stop holding, select an SAIL or BSAI cylinder. This SAIJ configuration uses a SUS304 rod and PT ports, and is dimensionally interchangeable with ISO 15552 cylinders.
Quick checklist
If you increase the pressure to 0.7MPa, the push force rises to 563N.
The rear adjuster screw acts as a mechanical stop that lets you trim the 100mm nominal stroke back by up to 75mm, resulting in a usable travel window of 25-100mm. It sets the end position but does not lock the load without continuous air pressure.
