About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-10S
The AirTAC SAIJ32X50-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 50 mm nominal stroke that can be fine-tuned down by up to 10 mm, creating a precise 40-50 mm usable travel window for commissioning without external stops. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and includes a magnet (-S) for position sensing. The extruded aluminum barrel houses sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid supply is routed through a PT tapered G1/8 port, and the standard mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-10S Is Used
End-Position Tuning
Dial in the exact 40-50 mm retract distance during machine commissioning to perfect part seating without machining new hard stops.
Product Changeover
Quickly trim the stroke by up to 10 mm on packaging lines when switching to slightly different product sizes or thicknesses.
Compact Assembly Stops
Use the 32 mm bore's 345 N pull force to precisely seat light components, relying on the rear screw for final position calibration.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N, or down to a smaller profile cylinder for lighter duties. The adjustable 40-50 mm travel window is ideal for variable end-stops and product changeovers, eliminating the need to swap cylinders or bolt on external stoppers. The rear adjuster acts purely as a travel stop and does not hold the load without live air—use an AirTAC SAIL or BSAI lock cylinder for fail-safe load holding. As a direct ISO 15552 replacement, match the 32 mm bore, 50 mm stroke, 10 mm adjuster, PT G1/8 port, and -S magnet.

- ✓ 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 SAIJ32AX50-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the 50 mm nominal stroke by up to 10 mm, providing a usable travel window of 40-50 mm. It only sets the end position and does not lock the load without continuous air pressure.
