About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-75
The AirTAC SAIJ32X270-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 270 mm travel by up to 75 mm. This creates a highly flexible 195-270 mm usable stroke window, letting you fine-tune the retract end position at commissioning without swapping out the barrel or adding bulky external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty precision tasks.
This SKU is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads on its G1/8 supply ports. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE solid-state switches if you add a magnet later. As an adjustable-stroke variant, it supports a specific mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-75 Is Used
Changeover Position Tuning
Dial in the exact retract distance within the 195-270 mm window during product size changeovers on a packaging line, eliminating the need to physically swap cylinders for different formats.
Machine Setup Calibration
Use the 75 mm adjustment range to perfectly square and align assemblies at commissioning, compensating for mechanical tolerances without fabricating custom external stopper blocks.
Light-Force Positioning
Leverage the 402 N push force and SUS420J2 stainless rod for precise, corrosion-resistant component placement in environments requiring clean, repeatable end-stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-75 the Right Cylinder?
Choose this 32 mm bore actuator when your application requires a 270 mm stroke but needs exact end-position tuning during machine setup or product changeover. If your process needs less force, stepping down is not an option in this series, but if you need significantly more thrust, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 270 mm stroke is substantial for a 32 mm rod, you should use an external guide to prevent side-load damage on the M10x1.25 rod thread.
The rear adjuster acts purely as a mechanical stop to set the travel end and relies on the variable air cushion to decelerate the load; it does not hold the load without live air pressure. For load-holding requirements without continuous pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 270 mm stroke, 75 mm adjustment, PT G1/8 ports, the appropriate mounting subset, and no magnet.

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 SAIJ32AX270-75 FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 75 mm from the nominal 270 mm stroke. This provides a usable travel window of 195-270 mm, which can be fine-tuned at commissioning without changing the cylinder or adding external stops.
At 0.5 MPa operating pressure, this 32 mm bore double-acting cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds between 30 and 800 mm/s.
