About the Airtac SAI40 Standard Air Cylinder SAI40BX75S
The AirTAC SAI40X75-S is a double-acting ISO 15552 profile cylinder engineered for direct compatibility with standardized mounting interfaces. Delivering a push force of 628 N at 0.5 MPa, this 40 mm bore unit is built for compact yet capable actuation tasks.
Equipped with a 75 mm stroke, this configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for CMSE/DMSE sensor integration. The extruded aluminum barrel features sensor grooves on both sides, and fluid connections use PT tapered threads.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX75S Is Used
Clamping Mechanisms
Provides reliable 628 N clamping force for securing medium-sized workpieces during machining or welding operations.
Package Diverters
Actuates short-stroke routing gates on packaging lines where fast 75 mm movements are needed to redirect products.
Gate Ejection
Pushes completed parts out of machining centers with precise force, utilizing the adjustable air cushions to prevent end-impact damage.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX75S the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm variant's 402 N output, but the 982 N force of a 50 mm bore would be excessive. The 75 mm stroke provides quick, short-travel actuation ideal for tight machine envelopes.
Because this standard cylinder does not hold its position upon loss of air pressure, implement an external pilot-operated check valve or specify the SAIL locking variant if mid-stroke safety is required. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard FA/FB flanges and TC trunnion mounts.
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 SAI40 Standard Air Cylinder SAI40BX75S FAQ
