About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X125-10S
The AirTAC SAIJ32X125-10-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 12mm carbon steel rod with an M10x1.25 thread. The built-in PT tapered port ensures a reliable pneumatic connection.
With a nominal 125mm stroke and a 10mm adjustment range, this SKU provides a usable travel window of 115-125mm. This allows precise end-position tuning at commissioning without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides, and the included magnet (-S) supports CMSE reed and DMSE electronic solid-state switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X125-10S Is Used
Precision End-Stop Tuning
Dial in the exact 115-125mm travel distance during machine commissioning to perfect part seating without adding external stopper blocks.
Product Size Changeover
Quickly adjust the rear screw by up to 10mm to accommodate slightly different product lengths on a packaging line.
Assembly Positioning
Use the 402N push force to drive light assembly tooling, relying on the fine stroke adjustment to prevent overtravel damage.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X125-10S the Right Cylinder?
Choose this 32mm bore when an application requires 402N push force at 0.5 MPa but demands variable end-stops for product changeovers. If your setup requires less force, stepping down is not an option in this series, but stepping up to a 40mm bore yields 628N. The rear adjuster acts purely as a travel stop for deceleration and is not a lock; the SAIJ32X125-10-S will not hold a load without live air. For load-holding requirements, consider the SAIL or BSAI series.
Because the 125mm stroke exceeds 300mm? No, but for any stroke over 300mm you would need an external guide to prevent side-loading. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The standard configuration includes a PT port, carbon steel rod, and a magnet for CMSE / DMSE sensors.

- ✓ 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 SAIJ32X125-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 125mm down to 115mm. This creates a 115-125mm usable travel window for fine-tuning the end position without changing the cylinder.
