Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-10S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 70mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-10S
The AirTAC SAIJ32X70-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a PT tapered port thread. By turning the rear adjustment screw, you can shorten the effective travel from the 70mm nominal stroke, providing a precise 60-70mm usable window for fine-tuning end positions.
This 32mm bore variant includes a built-in magnet (-S) for position sensing with AirTAC CMSE reed and DMSE electronic sensors. The piston rod is constructed from SUS420J2 stainless steel (option A) for improved corrosion resistance, and the extruded aluminum barrel eliminates tie-rod construction while maintaining standard ISO 15552 mounting dimensions.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-10S Is Used
Machine Changeover
Dial in the 60-70mm stroke window during product size transitions to set new end stops rapidly without swapping the cylinder.
End-Position Tuning
Trim up to 10mm of travel at commissioning to resolve minor mechanical clearances and achieve exact positioning.
Sensor Integration
Leverage the internal magnet with CMSE or DMSE switches to confirm retracted and extended positions in automated setups.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-10S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your application requires 402N of thrust at 0.5 MPa and exact end-position tuning without adding external stops. If your process demands less force, stepping down is not an option in the SAIJ series, but if you need higher force, the 40mm bore provides 628N at the same pressure. The rear adjuster acts solely as a travel stop to decelerate the piston; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32AX70-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder generates 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjustment screw allows you to shorten the 70mm nominal stroke by up to 10mm, creating a 60-70mm usable travel window. This stopper decelerates the piston at the end of travel but does not lock the load without continuous air pressure.
