About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-75S
The AirTAC SAIJ32X260-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the 260 mm nominal travel by up to 75 mm, creating a usable end-position window of 185 to 260 mm. Built with a SUS304 stainless steel rod and PT tapered ports, it generates 402 N of push force and 345 N of pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides to house CMSE reed and DMSE electronic switches.
Because the rear adjuster acts as a mechanical stop rather than a lock, it sets the retract deceleration point without holding the load pneumatically. For applications requiring position holding without live air pressure, consider the SAIL air-released lock or BSAI clamp-lock variants. This model supports a speed range of 30 to 800 mm/s and uses adjustable air cushions at both ends to manage impact energy.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 185 and 260 mm during commissioning without replacing the entire cylinder or adding external mechanical stops.
Product Size Changeover
Quickly adapt automated packaging lines to different product lengths by adjusting the rear stopper screw on the fly.
Sensor-Ready Positioning
Utilize the integrated magnet with DMSE electronic or CMSE reed sensors to confirm end-of-stroke positions across the adjusted travel range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-75S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N, or down if less travel is acceptable. The 75 mm adjustment window is ideal for machine setups requiring variable end-stops during product changeovers, eliminating the need to swap cylinders or bolt on external stops. At 260 mm of stroke, the 12 mm rod provides a sturdy interface, but long unsupported strokes still require an external guide to manage side loads. This SKU is dimensionally interchangeable per ISO 15552 and includes a magnet for position sensing.

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 SAIJ32BX260-75S FAQ
At 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 delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 260 mm nominal length, providing a usable travel window of 185 to 260 mm. This mechanical stop fine-tunes the end position but does not lock the load without live air.
