About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-100S
The AirTAC SAIJ32X240-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32 mm bore and a 240 mm nominal stroke, but the integrated adjusting screw allows you to trim the effective travel back by up to 100 mm. This creates a highly versatile 140-240 mm usable travel window, letting you dial in the exact retract end position during commissioning without swapping out the cylinder.
Delivering 402 N of push force at 0.5 MPa, this compact unit is built for precision. It includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and carries a magnet (-S) for position sensing via AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel provides sensor grooves on both sides, and the variable air cushions at both ends work alongside the rear stopper to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-100S Is Used
Machine Changeover
Rapidly adapt retract distances when switching between product sizes on a packaging line by dialing the 100 mm adjustment screw instead of re-mounting hardware.
Prototype Positioning
Fine-tune the 140-240 mm travel window during R&D commissioning to find the exact end-stop required for a new assembly process.
Variable End Stops
Use the rear stopper to set precise retract limits on automated test fixtures where the target position varies slightly between production runs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-100S the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa but demands flexible end-position tuning. If you need significantly more power, stepping up to the 40 mm bore yields 628 N of push force. The 100 mm adjustment range is exceptionally wide, making this SKU ideal for prototyping or machinery that frequently processes different product sizes. Instead of machining custom external stops, operators can turn the rear screw to shift the travel window between 140 and 240 mm on the fly.
Because the nominal stroke is 240 mm, the M10x1.25 rod should be guided if experiencing any lateral loading. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder will not hold its position without live air. For load-holding requirements without continuous pressure, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model uses a PT tapered port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options.

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 SAIJ32AX240-100S 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 adjusting screw acts as an external stopper that can shorten the effective stroke by up to 100 mm. This gives the 240 mm nominal stroke a usable travel window of 140 to 240 mm, which can be fine-tuned during setup without replacing the cylinder.
