About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-10S
The AirTAC SAIJ32X140-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 140 mm stroke that can be fine-tuned down by up to 10 mm, yielding a precise 130-140 mm usable travel window. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. A PT tapered port thread is standard, and the rear adjuster acts purely as a travel stop for end-position tuning, not as a load lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-10S Is Used
Machine Setup Fine-Tuning
Dial in the exact 130-140 mm retract position during commissioning to align tooling perfectly without machining new spacer blocks.
Product Changeover Stops
Quickly adjust the end-stop by up to 10 mm on a packaging line when handling slightly different carton lengths.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component placement in compact assemblies.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-10S the Right Cylinder?
Choose this 32 mm bore cylinder when you need 402 N of thrust at 0.5 MPa and the ability to dial in the retract end-position during commissioning without adding external stops. If your application requires less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 628 N of push force. The adjustable stroke is ideal for product changeovers on a line where a fixed-stroke SAI cylinder would require physical shimming.
Because the stroke is 140 mm, side-load stress is moderate, but always ensure the load is guided externally to protect the 12 mm rod. Remember that the rear adjuster only sets the travel end; it does not hold the load without live air. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.

- ✓ 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 SAIJ32BX140-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the 140 mm nominal stroke by up to 10 mm, creating a 130-140 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
