About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-10
The AirTAC SAIJ32X280-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 270-280 mm window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threading.
Because the adjuster acts as a retract-end stop rather than a locking mechanism, it decelerates the piston without holding the load absent live air pressure. The extruded aluminum barrel includes sensor grooves on both sides for straightforward positioning of CMSE reed or DMSE electronic solid-state switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-10 Is Used
Machine Changeover
Dial in the 270-280 mm travel window during product size transitions to set precise retract positions without adding external physical stops.
End-Position Tuning
Compensate for mechanical tolerance stack-up at commissioning by trimming the stroke up to 10 mm via the rear adjusting screw.
Light Part Ejection
Provides 402 N of push force at 0.5 MPa to reliably eject small parts off a conveyor line while allowing rapid stroke tweaks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-10 the Right Cylinder?
Choose this 32 mm bore when your application requires the exact end-position tuning that a fixed-stroke SAI cylinder cannot provide, allowing quick product changeovers without swapping hardware. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa.
At 280 mm of travel, this unit approaches the threshold where rod side-loading becomes a concern; an external guide is recommended to prevent premature seal wear. For any load-holding requirements without continuous air pressure, the rear stop is insufficient, and a SAIL pneumatic lock or BSAI clamp-lock cylinder should be specified instead. This SAIJ configuration supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set.

- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-10 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can output up to 82 kgf.
The rear adjuster acts as an external stopper that trims the effective stroke back by up to 10 mm, giving you a usable travel window of 270-280 mm. It sets the end position but does not lock the load without live air pressure.
