About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-20
The AirTAC SAIJ32X80-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 60 to 80 mm, allowing you to dial back the nominal 80 mm stroke by up to 20 mm during commissioning. This bore size delivers 345 N of pull force at 0.5 MPa, making it suitable for light-load positioning.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Configured here with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, it uses PT tapered port threading and operates at speeds from 30 to 800 mm/s. The rear adjuster acts purely as a mechanical stop to set the retract end position and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-20 Is Used
Machine Changeover
Dial in the 60-80 mm travel window during product size transitions to set new retract endpoints without replacing hardware.
End-Position Tuning
Fine-tune the final retract position during commissioning to absorb mechanical tolerances and achieve precise placement.
Light-Load Positioning
Leverage the 345 N pull force to move small actuators or stops, adjusting the travel distance on the fly for varied batch runs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-20 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping cylinders or adding external stops. If your process demands higher thrust, stepping up to the 40 mm bore yields 528 N of pull force at 0.5 MPa. Conversely, lighter duties might use a smaller profile cylinder.
The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers. Because the rear screw is a travel stop and not a lock, a plain SAIJ will not hold a load safely without live air; for true drop-prevention, consider the SAIL series or an external rod lock. This model is dimensionally interchangeable per ISO 15552, featuring a PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no standard 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 SAIJ32AX80-20 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm. This creates a usable travel window of 60 to 80 mm, letting you fine-tune the retract end position without modifying the cylinder mounting.
At a 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 of push force at 0.9 MPa.
