About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-75
The AirTAC SAIJ32X1000-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 925 to 1000 mm, letting you dial back the extend position by up to 75 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a standard carbon steel piston rod and M10x1.25 rod thread, this 32 mm bore unit uses a PT tapered G1/8 port. It supports variable air cushions at both ends to decelerate the payload smoothly. The rear screw acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-75 Is Used
Variable End-Stop Positioning
Fine-tune the extend position within the 925 to 1000 mm window during machine commissioning to achieve exact material placement without mechanical shims.
Product Size Changeover
Quickly adapt a long-stroke transfer arm to handle different product lengths on a packaging line by adjusting the rear stopper up to 75 mm.
Long-Stroke Setup Calibration
Dial in the precise end-of-travel point for a 1000 mm stroke actuator during initial equipment calibration to prevent overshoot.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-75 the Right Cylinder?
Choose this adjustable-stroke model when you need precise end-position tuning at machine setup without swapping cylinders or adding external stops. If your application requires less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore yields 628N push force at 0.5 MPa. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the adjuster.
Because this cylinder features a 1000 mm stroke, the 12 mm rod requires an external guide to prevent excessive side-loading and binding over long extensions. This SAIJ configuration is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ32X1000-75 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm, providing an adjustable travel window of 925 to 1000 mm. It functions as a mechanical stop to set the end position and does not lock the load without live air.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
