About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-40S
The AirTAC SAIJ32X180-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 140-180mm, enabling precise end-position tuning at commissioning without swapping the barrel. In the 32mm bore class, it generates 563N of push force and 345N of pull force at 0.5MPa, making it suitable for light-duty handling.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works directly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop for deceleration, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-40S Is Used
Product Changeover
Dial in the 140-180mm travel window during line changeovers to accommodate different package sizes without replacing the cylinder.
Machine Setup
Fine-tune the retract end-position during initial commissioning using the rear stopper, avoiding the need for external mechanical stops.
Variable End Stops
Set precise endpoints for light-duty pick-and-place tasks requiring up to 563N of push force at 0.7MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-40S the Right Cylinder?
Select this 32mm bore model when an application requires a 140-180mm stroke window and lower forces around 563N at 0.7MPa. If your process needs greater thrust, stepping up to the 50mm bore yields 1374N at the same pressure. Choose this adjustable SAIJ over a fixed SAI when you need variable end-stops for machine setup or product changeovers without adding external stops.
For load-holding without continuous air pressure, note that this cylinder's adjuster and air cushions function only as travel stops, not as a lock. In such cases, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. This SAIJ model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ32BX180-40S FAQ
The rear adjuster screw lets you shorten the effective travel by up to 40mm, creating a usable stroke window of 140-180mm. It acts as a mechanical stop to set the end position and does not lock the load without live air.
At 0.5MPa it provides 402N push and 345N pull force. At 0.7MPa the push force is 563N, and at 0.9MPa it reaches 724N.
