About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-50S
The AirTAC SAIJ32X425-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 425 mm nominal stroke that can be fine-tuned down by up to 50 mm, yielding a precise 375-425 mm usable travel window. Delivering 563 N of push force at 0.7 MPa, it fits compact automation setups requiring exact end-position tuning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides. It uses a PT G1/8 port and offers variable air cushioning at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-50S Is Used
Machine Changeover
Dial in the 375-425 mm travel window during product size transitions to set new end positions without physically replacing the cylinder.
End-Stop Calibration
Fine-tune the retract position at commissioning to achieve exact mechanical alignment, avoiding the need for external stopper blocks.
Assembly Line Indexing
Provides reliable 402 N push force at 0.5 MPa for moving small components, with adjustable travel to accommodate varying part dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-50S the Right Cylinder?
Choose this 32 mm bore when your application demands 563 N push force at 0.7 MPa; step down if lower force is acceptable, or up to a 40 mm bore (879 N push at 0.7 MPa) for heavier payloads. The adjustable stroke is selected over a fixed SAI cylinder when you need commissioning fine-tuning or product-size changeovers without swapping hardware. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). For a 425 mm stroke, ensure external guides support the load to prevent excessive rod side-loading.
The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL or BSAI cylinder. This SAIJ32X425-50-S is dimensionally interchangeable per ISO 15552 and includes a -S 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 SAIJ32BX425-50S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50 mm. This creates a 375-425 mm usable travel window, allowing you to fine-tune the end position at commissioning. The adjuster is a mechanical stop, not a lock, and the cylinder requires live air to hold position.
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At 0.7 MPa, the push force increases to 563 N. The maximum push force is 724 N at 0.9 MPa.
