About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-50S
The AirTAC SAIJ32X140-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -50 adjustment mechanism creates a usable travel window of 90-140mm, enabling precise end-position tuning without adding external stops.
This specific configuration features a SUS304 stainless steel rod (code B) and a PT tapered port thread, making it highly suitable for environments where corrosion resistance is paramount. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S model, it contains a magnet ready for CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts strictly as a travel stop to set deceleration, not as a load-holding lock.

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 SAIJ32BX140-50S Is Used
Machine Changeover
Dial in the 90-140mm travel window on the fly to accommodate different product lengths during line changeovers without swapping hardware.
Commissioning Calibration
Fine-tune the retract end-position during initial setup, using the rear stopper to perfect the stroke without adding external shims.
End-Stop Trimming
Achieve exact positioning for automated assembly tasks by adjusting the effective stroke up to 50mm to meet exact dimensional tolerances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-50S the Right Cylinder?
Choose this 32mm bore adjustable-stroke cylinder when your application requires exact end-position tuning at commissioning or during product-size changeovers, rather than relying on a fixed-stroke SAI variant. For load-holding without live air pressure, note that the SAIJ adjuster is only a stop; you would need an external rod lock, a pilot-operated check valve, or a related AirTAC type like SAIL or BSAI. This SAIJ32X140-50-S is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The 12mm rod and M10x1.25 thread handle moderate side loads, but for any stroke over 300mm, an external guide is recommended.

- ✓ 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 SAIJ32BX140-50S FAQ
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 50mm. This creates a usable travel window of 90-140mm, allowing you to fine-tune the retract end-position without replacing the cylinder.
At 0.7MPa, the push force increases to 563N.
