About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-30
The AirTAC SAIJ32X230-30 is a double-acting, single-rod ISO 15552 profile cylinder engineered with a rear mechanical stopper. This adjuster allows you to fine-tune the retract end-position on the fly, providing a usable travel window of 200 to 230 mm without needing to physically swap the actuator or bolt on external stops. It delivers 402 N of push force and 345 N of pull force at a 0.5 MPa operating pressure.
Built with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, this 32 mm bore actuator features PT tapered port threads (G1/8) and variable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches, though this specific SKU is supplied without a magnet.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-30 Is Used
Machine Changeover
Dial in the exact retract position within the 200-230 mm window when switching between product sizes on a packaging line, eliminating the need to physically swap cylinders or add spacer blocks.
End-Position Tuning
Fine-tune the final resting point during commissioning to compensate for mechanical tolerance stack-ups, ensuring precise alignment without altering the fixed mechanical hard stops.
Variable Diverting
Adjust the stroke length on the fly for sorting mechanisms or diverters that need to accommodate different package profiles without reprogramming the machine logic.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-30 the Right Cylinder?
Select this 32 mm bore model when your application requires 402 N of push force at 0.5 MPa and demands a variable end-stop. If your setup requires less force, stepping down to a 25 mm bore might suffice, but if you need to move heavier loads, stepping up to a 40 mm bore provides 628 N of push force at the same pressure. The adjustable stroke is ideal for machine changeovers and product-size variations, allowing precise commissioning without the rigid constraints of a fixed-stroke SAI cylinder.
Because the nominal stroke is 230 mm, ensure your mounting arrangement supports the rod adequately to prevent excessive side-loading. For load-holding requirements, note that the rear adjuster acts only as a travel stop and does not lock the load without live air pressure; for true position holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and supports a mounting subset of 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 SAIJ32AX230-30 FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to trim the effective stroke by up to 30 mm. This creates a usable travel window of 200 to 230 mm, letting you set the exact retract end-position during commissioning without replacing the cylinder.
At a standard 0.5 MPa operating pressure, the SAIJ32X230-30 provides 402 N of push force and 345 N of pull force. If higher pressures are used, the push force increases to 563 N at 0.7 MPa and 724 N at 0.9 MPa.
