About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-100S
The AirTAC SAIJ32X250-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 100 mm. This creates a highly versatile 150-250 mm usable stroke window, letting you dial in the exact retract position without swapping hardware. It delivers 402 N of push force at 0.5 MPa, making it well-suited for lighter-duty precision tasks.
Equipped with a SUS420J2 stainless steel rod (code A) and a magnet for position sensing, this model integrates seamlessly with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, while the PT G1/8 port ensures straightforward pneumatic integration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-100S Is Used
Machine Changeover
Quickly adapt retract distances when switching product sizes on a packaging line, using the 100 mm adjustment window to avoid physical hardware changes.
End-Position Tuning
Fine-tune the exact end-of-stroke position during commissioning to perfectly seat delicate components without adding external mechanical stops.
Adjustable Ejection
Vary the ejection throw distance on an assembly fixture to accommodate different part depths, relying on the 150-250 mm usable travel window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-100S the Right Cylinder?
Choose this 32 mm bore when you need precise retract-end tuning during commissioning or product changeovers, avoiding the need to bolt on external stops. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the nominal stroke is 250 mm, ensure adequate external guiding to prevent excessive side-loading on the rod.
When specifying a replacement, verify the 250 mm nominal stroke, 100 mm adjustment range, PT G1/8 port, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ32AX250-100S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The operational speed range is 30-800 mm/s.
The rear adjuster screw allows you to shorten the 250 mm nominal stroke by up to 100 mm, providing a usable travel window of 150-250 mm. It functions as a physical stop and does not lock the load without air pressure.
