About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-50
The AirTAC SAIJ32X50-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 0 to 50 mm. Delivering 402 N of push force at 0.5 MPa, it utilizes a SUS420J2 stainless steel rod for enhanced durability against lateral stress and corrosive environments.
This adjustable model features a PT tapered port (G1/8) and dual-sided sensor grooves. By turning the rear stopper screw, operators can dial in the exact end-of-stroke position during commissioning without adding bulky external stops or swapping the cylinder.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-50 Is Used
Precision End-Stop Tuning
Dial in the exact 0 to 50 mm travel distance during machine commissioning to accommodate varying material thicknesses without external shims.
Product Size Changeover
Quickly adjust the retract end-position on packaging lines when switching between different product formats, minimizing downtime.
Light-Duty Clamping
Leverage the 402 N push force at 0.5 MPa for delicate holding tasks where the physical stopper prevents over-travel damage.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-50 the Right Cylinder?
Choose this 32 mm bore when an application requires precise variable end-stops within a compact 50 mm envelope. If your process demands higher clamping power, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The SAIJ32X50-50 is dimensionally interchangeable per ISO 15552 and is configured with a PT port thread, SUS420J2 rod material, and no magnet.
Because the rear adjuster functions strictly as a mechanical travel stop and not a lock, it will not hold a load without live air pressure. For applications requiring true fail-safe load holding, consider the AirTAC SAIL pneumatic lock series or an external rod lock. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32AX50-50 FAQ
At an operating pressure of 0.5 MPa, 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.
The rear adjuster acts as a mechanical stop that trims the effective stroke by up to 50 mm, creating a 0 to 50 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
