About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-75
The AirTAC SAIJ32X275-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 200 to 275 mm. It delivers a 0.5 MPa push force of 402 N and uses a PT tapered port with a 12 mm rod. The SUS304 stainless steel rod material provides excellent corrosion resistance for harsh or washdown environments.
This adjustable-stroke design allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts strictly as a travel stop to set deceleration and is not a lock; for load-holding without live air pressure, consider the SAIL or BSAI series. It supports AirTAC CMSE reed and DMSE electronic sensors via dual side barrel grooves.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-75 Is Used
Machine Setup & Changeover
Dial in the exact 200-275 mm travel window during commissioning or product changeovers without machining new hard stops.
Variable End-Stop Positioning
Ideal for assembly lines processing multiple part lengths, letting operators fine-tune the retract position on the fly.
Corrosive Environment Actuation
The SUS304 stainless steel rod handles lab or washdown applications where standard carbon steel rods would fail.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-75 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa (or 563 N at 0.7 MPa) and a highly variable end-stop. If you need more thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. The 75 mm adjustment range is perfect for product-size changeovers on a line, whereas a fixed-stroke SAI cylinder is better for repetitive single-cycle tasks.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 275 mm stroke, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 275 mm stroke is relatively long for a 32 mm rod, an external guide is recommended to prevent excessive side-load deflection.
Quick checklist
- ✓ 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 SAIJ32BX275-75 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 75 mm, creating a 200-275 mm usable window. It acts as a physical stop to set the end position and deceleration, but it does not lock the load without live air.
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.7 MPa the push force increases to 563 N.
