About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-75S
The AirTAC SAIJ32X290-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 215-290 mm usable travel window. By turning the external stopper screw, you fine-tune the retract end position at commissioning without swapping hardware or adding external stops. It delivers 402 N of push force at 0.5 MPa and uses a SUS420J2 stainless steel rod for improved corrosion resistance.
This model includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the standard extruded aluminum barrel sensor grooves. The 12 mm rod and M10x1.25 thread handle moderate side loads, but the 290 mm length means an external guide is recommended to prevent rod wear. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-75S Is Used
Machine Changeovers
Dial in the 215-290 mm travel window during product size transitions without machining new hard stops or replacing the cylinder.
End-Position Tuning
Trim up to 75 mm off the retract stroke to perfectly time the pickup or release point of a delicate assembly process.
Variable End Stops
Set multiple retract endpoints on a single line by adjusting the rear screw, allowing one cylinder to serve multiple fixture lengths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-75S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N push force at 0.5 MPa but still needs travel flexibility. If your process demands higher clamping power, stepping up to the 40 mm bore yields 628 N. Select this adjustable SAIJ over a fixed SAI when handling product-size changeovers on a single line, as the 75 mm trim range easily absorbs variance.
Because the 290 mm stroke exceeds 300 mm when combined with the adjuster travel, always support the load with an external guide to protect the 12 mm rod. The rear adjuster acts only as a travel stop and deceleration point; it does not hold the load without live air. For true fail-safe load holding, use a SAIL pneumatic lock or BSAI clamp-lock cylinder. This PT-ported, magnet-equipped unit is dimensionally interchangeable per ISO 15552.

- ✓ Required force at your working pressure
- ✓ 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 SAIJ32AX290-75S FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw lets you reduce the 290 mm nominal stroke by up to 75 mm, creating a 215-290 mm usable travel window. It functions as a mechanical stop, not a lock, so it cannot hold the load without live air pressure.
