About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-75
The AirTAC SAIJ32X350-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 350 mm stroke with an adjustable travel window of 275-350 mm, allowing you to dial back the extend position by up to 75 mm during commissioning. This bore delivers 402 N of push force at 0.5 MPa and uses a 12 mm carbon steel rod with an M10x1.25 thread.
This SKU features a PT tapered port (G1/8) and an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified, position sensing would require external mounts rather than internal CMSE or DMSE switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-75 Is Used
Machine Changeover
Dial in the exact end-stop for different product sizes on a packaging line without swapping out the entire cylinder assembly.
End-Position Tuning
Fine-tune the retract position during commissioning to perfect a 275-350 mm travel window, compensating for mechanical tolerances.
Variable End Stops
Adjust the stroke length on the fly for automated test fixtures that require different extension distances per cycle.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-75 the Right Cylinder?
Choose this 32 mm bore if your application requires 402 N of push force at 0.5 MPa (or 724 N at 0.9 MPa) and needs precise end-position tuning without adding external stopper blocks. If your changeover requirements are less demanding, a fixed-stroke SAI32X350 avoids the adjuster entirely, while stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa for heavier loads. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true fail-safe holding, consider an SAIL or BSAI locking cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 350 mm stroke, up to 75 mm adjustment, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 350 mm stroke is relatively long for this 12 mm rod, an external guide is recommended to prevent excessive side-loading and rod deflection.

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 SAIJ32AX350-75 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm, providing a usable travel window of 275-350 mm. It acts as a mechanical stop to fine-tune the end position without changing the cylinder.
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, it delivers up to 801 kgf.
