About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-30S
The AirTAC SAIJ32X900-30-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 900mm nominal stroke that can be fine-tuned down by up to 30mm, creating an exact 870-900mm usable travel window. This built-in adjustability allows operators to dial in end positions during commissioning without adding external stops.
Configured with an SUS420J2 stainless steel rod (code A) and a magnet for position sensing, this model accepts CMSE reed and DMSE electronic switches in its dual-side sensor grooves. The 12mm rod and M10x1.25 thread provide a robust interface, while the PT tapered port threads ensure a secure pneumatic connection. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions for straightforward interchangeability.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-30S Is Used
Changeover Calibration
Dial in the 870-900mm travel window during product size changeovers without physically swapping the cylinder or shimming external stops.
Long-Stroke Diverting
Fine-tune the retract position of a diverter arm on a 900mm stroke, ensuring precise alignment without mechanical fabrication.
End-Stop Trimming
Trim up to 30mm off the nominal stroke during machine commissioning to perfectly synchronize tooling coordinates.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-30S the Right Cylinder?
Choose this 32mm bore when you need precise retract positioning that a fixed-stroke SAI cannot provide. If your application requires greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. Because this cylinder features a 900mm stroke, the extended 12mm rod is susceptible to side-loading; always use an external guide rail to prevent binding and premature seal wear. To match this exact ISO 15552 footprint, specify the 32mm bore, 900mm stroke, 30mm adjustment, PT ports, and the -S magnet.
The rear adjuster acts strictly as a travel stop to set the retract end position, not as a locking device. It cannot hold a load without continuous live air pressure. If your setup requires true load-holding in the event of air loss, consider an AirTAC SAIL pneumatic lock cylinder or an external rod lock instead. The mounting hardware is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ Required force at your working pressure
- ✓ 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 SAIJ32AX900-30S FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82kgf.
The rear adjuster screw lets you shorten the 900mm nominal stroke by up to 30mm, providing a usable travel window of 870-900mm. It functions as a mechanical stop to set the end position and does not lock the load without live air.
