About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-50
The AirTAC SAIJ32X300-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and uses a PT tapered port with a 12mm SUS420J2 stainless steel rod. The built-in rear stopper allows you to fine-tune the effective travel down from the 300mm nominal stroke, creating a precise 250-300mm usable window for product changeovers without adding external stops.
Because the 300mm stroke is relatively long for a 32mm bore, the M10x1.25 rod thread and 12mm rod should be paired with an external guide to prevent excessive side-loading. The rear adjuster acts purely as a travel stop and works alongside the 27mm variable air cushions at both ends to decelerate the load, but it does not hold the position without live air pressure. For load-holding without continuous pressure, consider an external rod lock or the related SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-50 Is Used
Product Changeovers
Dial in the 250-300mm travel window during line changeovers to accommodate different package lengths without swapping the cylinder.
End-Position Tuning
Fine-tune the retract stopper during initial commissioning to dial out mechanical tolerance stack-up in your fixture.
Variable End Stops
Set precise retract positions for multi-stage assembly processes directly at the rear of the ISO 15552 profile barrel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-50 the Right Cylinder?
Choose this 32mm bore when your application requires the 402N push force at 0.5 MPa. If your setup needs more thrust, stepping up to the 40mm bore yields 628N. The SAIJ32X300-50 is selected over a fixed-stroke SAI cylinder when you need variable end-stops for machine commissioning or accommodating multiple product sizes on one line. To match this exact configuration, specify the 32mm bore, 300mm stroke, 50mm adjustment, PT port thread, SUS420J2 (A) rod material, and no magnet. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ 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 SAIJ32AX300-50 FAQ
An external adjusting screw at the rear acts as a mechanical stopper, allowing you to shorten the effective travel by up to 50mm. This creates a usable 250-300mm stroke window without replacing the cylinder.
At 0.5 MPa operating pressure, the 32mm bore provides a push force of 402N and a pull force of 345N. The maximum push force is 724N at 0.9 MPa.
