About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-20S
The AirTAC SAIJ32X375-20-S is a double-acting, extruded aluminum profile cylinder dimensionally interchangeable per ISO 15552. It features a rear adjuster screw that creates a usable travel window of 355-375 mm from the 375 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod for superior wear resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
This model uses PT tapered port threads (G1/8) and provides variable air cushions at both ends to decelerate the load. The rear stopper sets the travel limit but does not lock the load without live air pressure; for position holding, consider SAIL or BSAI types. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-20S Is Used
Machine Changeover
Dial in the 355-375 mm travel window during product size transitions to set new end positions quickly without swapping hardware.
Commissioning Fine-Tune
Use the rear stopper screw to adjust the retract end position precisely during initial machine setup rather than machining external stops.
Variable End Stops
Achieve exact end-of-stroke positioning within the 20 mm adjustment range for automated assembly processes requiring strict tolerances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-20S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa and a 355-375 mm stroke window. If your machine needs more power, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The adjustable stroke is selected over a fixed SAI cylinder when you need to fine-tune end positions during commissioning or product changeovers without adding external stops.
For this 375 mm stroke, the 12 mm rod diameter should be guided externally to prevent side-load damage, as long unsupported strokes require additional support. To replace an ISO 15552 cylinder, match the 375 mm stroke, 20 mm adjustment, PT G1/8 port, and -S magnet. Note that SAIJ omits FB, CA, CB, and CR mounts, utilizing only the Basic, FA, LB, TC, FTC, TCM1, and TCM2 set.

- ✓ 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 SAIJ32AX375-20S FAQ
It provides 402 N of push force and 345 N of pull force at 0.5 MPa, scaling up to 724 N push force at 0.9 MPa.
The rear adjuster screw trims the 375 mm nominal stroke, creating a 355-375 mm usable travel window. It acts as a travel stop and does not hold the load without live air.
