About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-75
The AirTAC SAIJ32X75-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel anywhere within a 0-75 mm window. Delivering 402 N of push force at 0.5 MPa, it is built around an extruded aluminum barrel with sensor grooves on both sides. This configuration uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and accepts PT tapered port threads.
Because the adjustment range equals the nominal stroke, you can dial the extension down to a near-zero stroke without swapping hardware. The rear screw acts purely as a mechanical stop to set the end position and relies on the variable air cushion for deceleration; it does not lock or hold the load without live air. For position holding without pneumatic pressure, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-75 Is Used
Product Changeovers
Dial in the exact extension length on the fly when switching between product sizes on a packaging line, using the 0-75 mm rear stopper to avoid repositioning cylinder mounts.
End-Position Tuning
Fine-tune the final approach of a small clamping or pressing jaw during commissioning without adding bulky external physical stops to the machine frame.
Variable Feed Stops
Set precise material feed distances in automated assembly equipment where the required travel length varies between different production runs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-75 the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N push force at 0.5 MPa but demands highly variable end-stops; if you need greater thrust, stepping up to the 40 mm bore yields 628 N at the same pressure. The SAIJ32X75-75 is ideal for machine setups requiring frequent product changeovers, replacing the need for fixed-stroke SAI cylinders or external stops. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Operating speed ranges from 30-800 mm/s.

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 SAIJ32AX75-75 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke anywhere within a 0-75 mm window. It sets the travel end and relies on the air cushion for deceleration, but it does not hold the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ32X75-75 provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
