About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-75S
The AirTAC SAIJ32X280-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a 402N push force at 0.5 MPa, utilizing a 12mm rod and G1/8 port. By turning the rear stopper screw, you can trim the nominal 280mm travel back by up to 75mm, yielding a precise 205-280mm usable stroke window for on-the-fly end-position tuning.
This unit includes a SUS304 stainless steel rod (option B) for enhanced corrosion resistance and is equipped with a magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors in the dual-sided barrel grooves. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-75S Is Used
Product Changeovers
Dial in the 205-280mm travel window during product size transitions on a packaging line without swapping cylinders.
End-Stop Tuning
Fine-tune the retract end-position at commissioning to perfect a delicate pressing or pushing operation.
Sensor Integration
Leverage the built-in magnet with DMSE solid-state sensors in the dual grooves for precise position feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-75S the Right Cylinder?
Choose this 32mm bore when you need lighter forces up to 402N at 0.5 MPa, or step up to the 40mm bore for 628N if your payload increases. The adjustable stroke is ideal for machine changeovers where the exact end-stop changes per product run, avoiding the need to physically swap out a fixed-stroke SAI cylinder or bolt on external stops. Because the 280mm stroke exceeds 300mm, ensure you use an external guide to prevent excessive side-loading on the 12mm rod. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI series cylinder. To replace an ISO 15552 cylinder, match the 32mm bore, 280mm stroke, PT tapered G1/8 port, the SAIJ mounting set, and the -S magnet.

- ✓ Magnet (-S) for sensors?
- ✓ 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 SAIJ32BX280-75S FAQ
At 0.5 MPa, it provides a 402N push force and a 345N pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw lets you shorten the 280mm nominal stroke by up to 75mm, creating a 205-280mm usable travel window to set the exact end-position without adding external stops.
