About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-10S
The AirTAC SAIJ32X140-10-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 130-140 mm, allowing you to dial back the 140 mm nominal stroke by up to 10 mm during commissioning.
This variant includes an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-10S Is Used
Product Changeover
Dial in the 130-140 mm travel window during machine setup to instantly adapt to slightly different product lengths without changing the cylinder.
End-Position Tuning
Use the 10 mm rear adjuster screw to precisely set the retract end-stop during commissioning, eliminating the need to bolt on external physical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-10S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when you need precise end-position tuning without swapping out physical components or adding external stops. Conversely, if you need a smaller footprint, ensure your force requirements are below the 32 mm capacity.
The rear adjuster allows you to fine-tune the 130-140 mm travel window to accommodate product changeovers on a machine. Because this SAIJ model lacks a locking mechanism, it cannot hold a load without continuous air pressure; for fail-safe load holding, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 32 mm bore, 140 mm stroke, 10 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and -S magnet specifications.

- ✓ 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 SAIJ32AX140-10S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 140 mm nominal stroke by up to 10 mm, creating a 130-140 mm usable travel window. It only sets the end position and does not lock or hold the load without live air pressure.
