About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-40S
The AirTAC SAIJ32X280-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 280mm nominal stroke that can be fine-tuned down by up to 40mm, giving you a precise 240-280mm usable travel window during commissioning.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet for CMSE and DMSE sensors. The extruded aluminum barrel provides standard ISO 15552 mounting dimensions, while the PT tapered port and M10x1.25 rod thread match the 32mm bore specification.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-40S Is Used
Product Changeover
Dial in the 240-280mm travel window on packaging lines to accommodate different carton sizes without physically swapping the actuator.
End-Stop Calibration
Fine-tune the retract position during machine setup to avoid mechanical hard stops, relying on the rear screw for exact positioning.
Sensor-Driven Handling
Leverage the integrated magnet with DMSE electronic sensors to confirm mid-stroke positions on small automated assembly stations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-40S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning without swapping cylinders or adding external stops; for higher force needs, stepping up to the 40mm bore provides 628N of push force at 0.5 MPa. Because the 280mm stroke is relatively long for this bore size, an external guide is recommended to prevent excessive side-loading on the M10x1.25 rod.
The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for dead-end load holding, consider an external rod lock or the SAIL series. When replacing an ISO 15552 cylinder, match the 32mm bore, 280mm stroke, 40mm adjustment, PT port, and -S magnet. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ 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 SAIJ32BX280-40S FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At a maximum 1.0 MPa operating pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 40mm from the 280mm nominal length, creating a 240-280mm travel window. It functions as a mechanical stop for end-position tuning and is not a locking device.
