About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-100
The AirTAC SAIJ32X500-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. Its 500mm nominal stroke can be dialed back by up to 100mm, providing a usable travel window of 400 to 500mm for precise end-position tuning during commissioning. Delivering 402N of push force at 0.5MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for direct CMSE reed or DMSE electronic switch mounting. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-100 Is Used
Machine Setup Changeover
Fine-tune the 400 to 500mm travel window during product changeovers without physically swapping out the cylinder or adding external stopper blocks.
Variable End Stops
Adjust the retract position on the fly to accommodate varying package sizes moving down a packaging line, ensuring precise positioning.
Light-Force Positioning
Utilize the 402N push force at 0.5MPa for delicate assembly tasks where a hard mechanical stop is preferred over relying solely on pneumatic cushions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-100 the Right Cylinder?
Choose this 32mm bore when you need 402N push force at 0.5MPa and a highly flexible end-stop, avoiding the need to swap cylinders for minor position changes. If your application requires higher thrust, stepping up to the 40mm bore yields 628N at 0.5MPa. Because the 500mm stroke is substantial for a 32mm rod, an external guide rail is recommended to prevent excessive side-loading and premature seal wear.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series. This model uses PT tapered ports. To replace an ISO 15552 cylinder, match the 32mm bore, 500mm stroke, 100mm adjustment, PT port thread, and your required mounting interface.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ 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 SAIJ32AX500-100 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm. This means the 500mm nominal stroke can be mechanically trimmed to any travel length between 400 and 500mm to set the exact retract end-position.
At an operating pressure of 0.5MPa, the SAIJ32X500-100 provides 402N of push force and 345N of pull force. At the maximum pressure of 1.0MPa, it can deliver up to 801N of push force.
