About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-75S
The AirTAC SAIJ32X190-75-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 190mm nominal stroke that can be fine-tuned down by up to 75mm, creating a usable travel window of 115-190mm. This wide adjustment band is ideal for dialing in exact end positions during machine commissioning without swapping hardware.
Built with a SUS304 stainless steel rod (option B), this model handles corrosive environments better than standard carbon steel. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed or DMSE electronic switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. It operates at speeds from 30-800mm/s and uses a PT tapered G1/8 port.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-75S Is Used
Product Changeover
Quickly dial in the 115-190mm stroke window during format changes on packaging lines without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end-stop during machine commissioning to achieve exact material feeding distances using the 75mm adjustment screw.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for light-duty positioning tasks in washdown or chemical exposure areas without compromising the 402N thrust.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-75S the Right Cylinder?
Choose this 32mm bore when you need precise retract positioning over a 115-190mm range but only have 402N (0.5MPa) of push force available. If your application requires greater thrust, stepping up to the 40mm bore yields 628N. Select the SAIJ adjustable type over a fixed SAI cylinder when machine setups involve frequent product changeovers or variable end-stops. For strokes of 300mm or more, external guides are recommended to manage side load, though this 190mm unit is well within standard limits.
Remember that the rear adjuster acts strictly as a mechanical stop to set deceleration and end position; it does not hold the load without live air. For dead-pilot or fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. This SAIJ32X190-75-S is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB, CA, CB, CR). Ensure your plumbing matches the PT G1/8 port thread.

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 SAIJ32BX190-75S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to shorten the 190mm nominal stroke by up to 75mm, providing an effective travel range of 115-190mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
