About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-100S
The AirTAC SAIJ32X225-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to trim the effective travel back by up to 100 mm. This yields a highly flexible usable stroke window of 125 to 225 mm, ideal for dialing in exact end positions during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty workholding tasks.
This unit includes an integrated magnet for position sensing via CMSE reed or DMSE solid-state switches riding in the dual sensor grooves. It is built with a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-100S Is Used
Machine Commissioning Tuning
Dial in the exact end position during setup by turning the rear adjuster, fine-tuning the travel window from 125 to 225 mm without swapping cylinders.
Product Size Changeover
Adapt to different product lengths on a conveyor line quickly by adjusting the stroke stopper up to 100 mm to accommodate varying package dimensions.
Light Workholding Stops
Use the 402 N of push force at 0.5 MPa to position light parts accurately, relying on the rear screw to set the precise retraction endpoint.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-100S the Right Cylinder?
Select this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and a widely variable end-stop. The 100 mm adjustment range is excellent for product changeovers on a line, removing the need to physically swap cylinders or bolt on external stops. If you need to step up to 628 N of push force, move to the 40 mm bore. For holding a load mechanically without continuous air pressure, select the SAIL or BSAI series instead of relying on this rear stopper.
To replace an ISO 15552 cylinder, match the 32 mm bore, 225 mm nominal stroke, 100 mm adjustment, PT port threads, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 225 mm stroke is relatively long for a 32 mm bore, ensure you provide an external guide to prevent excessive rod side-loading and premature seal wear.

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 SAIJ32AX225-100S FAQ
The rear adjuster acts as an external mechanical stop that shortens the effective travel. For this SAIJ32X225-100-S model, you can trim the 225 mm nominal stroke back by up to 100 mm, providing a usable travel window of 125 to 225 mm.
At a 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 82 kgf.
