The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 25mm 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 SAIJ32X25-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 25 mm nominal stroke and a 20 mm adjustment range, it provides a usable travel window of 5 to 25 mm for precise end-position tuning.
This adjustable model allows you to fine-tune the retract position at commissioning without swapping hardware or adding external stops. The rear screw acts purely as a travel stop and works alongside the variable air cushions at both ends, but it does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.

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.
Dial in the exact 5 to 25 mm retract position during machine commissioning to accommodate varying material thicknesses without external stopper blocks.
Quickly adjust the stroke window on automated lines when switching between different product sizes, minimizing downtime and avoiding cylinder swaps.
Apply up to 402 N of clamping force at 0.5 MPa in compact assemblies where the exact touching distance must be tweaked on the fly.
Choose this 32 mm bore when your application requires a very short travel distance that must be dialed in exactly on-site, replacing the need for fixed-stroke SAI cylinders. For load-holding without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; consider the SAIL or BSAI series instead. Configuration: 32 mm bore, 25 mm stroke, 20 mm adjust, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounts, no magnet.
Quick checklist
The rear adjuster screw lets you shorten the effective travel from the nominal 25 mm down to 5 mm, creating a 5-25 mm usable window. It functions as a mechanical stop to set the exact end position and is not a lock.
