About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10S
The AirTAC SAIJ32X275-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a 402N push force at 0.5 MPa and provides a usable travel window of 265 to 275 mm, letting you dial in the exact end position without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch mounting.
This variant is equipped with a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic switches. It utilizes the standard SAIJ mounting set, omitting FB, CA, CB, and CR brackets in favor of Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10S Is Used
Machine Changeover
Quickly fine-tune the 265-275mm travel window during product size changes on a packaging line without swapping out the entire actuator.
End-Stop Calibration
Dial in the exact retract position during machine commissioning using the rear adjuster, ensuring perfect alignment of the 12mm rod.
Assembly Positioning
Move lightweight components with 402N of push force while relying on the SUS420J2 stainless rod for durability in industrial environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10S the Right Cylinder?
Choose this 32mm bore actuator when your application requires 402N of push force at 0.5 MPa and precise end-position tuning during commissioning. If your setup demands greater thrust, stepping up to the 40mm bore yields 628N, while dropping to a smaller frame reduces the footprint. The 10mm rear adjuster screw acts purely as a travel stop to fine-tune the 275mm stroke; it does not hold the load without live air. For load-holding requirements without pneumatic pressure, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 32mm bore, 275mm stroke, 10mm adjustment range, PT G1/8 port, and the -S magnet requirement. Because the stroke is 275mm, the 12mm diameter rod and M10x1.25 thread may experience side-loading on long unsupported spans; always use an external guide rail to prevent premature wear. Operating speed ranges from 30 to 800 mm/s.

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 SAIJ32AX275-10S FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 801N of push force.
The rear adjusting screw allows you to shorten the effective travel by up to 10mm, creating a usable stroke window of 265 to 275mm. This stopper fine-tunes the end position but does not lock or hold the load without continuous air pressure.
