About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-10S
The AirTAC SAIJ32X270-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 260 to 270 mm. Delivering 402 N of push force at 0.5 MPa, it fits light-duty positioning tasks perfectly. The SUS420J2 stainless steel rod (option A) elevates corrosion resistance compared to standard carbon steel.
This model includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the extruded aluminum barrel's dual sensor grooves. The rear stopper screw allows precise end-position tuning at commissioning without adding external stops, acting solely as a travel limiter rather than a load-holding brake.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-10S Is Used
End-Position Tuning
Dial in the exact 260-270 mm travel limit during machine commissioning to perfect product placement without external stopper blocks.
Rapid Changeover
Adjust the retract stop on the fly when switching product sizes on a conveyor line, saving downtime on physical actuator swaps.
Light-Force Positioning
Leverage the 402 N thrust and SUS420J2 stainless rod for precise, corrosion-resistant component handling in varied environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-10S the Right Cylinder?
Select this 32 mm bore when you need 402 N push force and a 260-270 mm variable end-stop; step down if you require less force, or up to a 40 mm bore (628 N) for heavier loads. The adjustable stroke is chosen over a fixed SAI cylinder to simplify machine setup and product changeovers, letting you dial in the exact 10 mm trim without swapping the actuator body.
Because the nominal stroke is 270 mm, an external guide is recommended to prevent excessive side-load on the M10x1.25 rod thread. For any load-holding requirements without live air pressure, this cylinder's adjuster will not suffice—consider an AirTAC SAIL or BSAI lock model instead. Replacement requires matching the 32 mm bore, 270 mm stroke, 10 mm adjuster, PT G1/8 port, and -S magnet.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ32AX270-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N at 0.9 MPa.
A rear adjuster screw trims the retract stroke by up to 10 mm, creating a 260-270 mm usable travel window. This stopper only sets the end position and does not lock the load without live air.
