About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-50S
The AirTAC SAIJ32X50-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a PT tapered port with a 12mm SUS420J2 stainless steel rod. The built-in magnet supports CMSE reed and DMSE electronic sensors.
This specific SKU provides a 0-50mm usable travel window from its 50mm nominal stroke. The rear adjuster acts as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and relies on adjustable air cushions at both ends for deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-50S Is Used
Machine Changeovers
Dial in the retract stroke from 0 to 50mm during product size changeovers without physically swapping the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the exact end-of-stroke position during machine commissioning to synchronize pick-and-place movements within a tight 50mm window.
Sensor-Ready Testing
Utilize the integrated magnet with DMSE electronic sensors to verify intermediate positions during variable stroke testing routines.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-50S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning within a 0-50mm travel window. If your machine needs higher thrust, step up to the 40mm bore which provides 628N push force at 0.5 MPa. The 12mm rod and M10x1.25 thread handle moderate side loads, but long unsupported strokes still require an external guide.
Select the adjustable SAIJ over a fixed SAI cylinder when accommodating product size changeovers on a single line. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ will not hold a load without live air. For fail-safe load holding, consider the SAIL or BSAI series. This SAIJ32X50-50-S is dimensionally interchangeable per ISO 15552 and includes the -S magnet for position sensing.

- ✓ 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 SAIJ32AX50-50S FAQ
It provides 402N of push force and 345N of pull force at 0.5 MPa. The operational speed range for this 32mm bore cylinder is 30-800 mm/s.
The rear adjuster screw allows you to mechanically shorten the effective stroke from 0 up to 50mm. It functions as a physical stop for end-position tuning and does not lock the load without continuous air pressure.
