About the Airtac SAI40 Standard Air Cylinder SAI40BX110
The AirTAC SAI40X110 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 110mm stroke. It generates 628N of push force at 0.5 MPa, extending to 879N at 0.7 MPa, making it well-suited for mid-range industrial handling tasks.
This specific configuration utilizes a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. It connects via PT tapered ports and lacks a magnet, meaning it is optimized for pure actuation without requiring electronic position sensing.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX110 Is Used
Package Diverting
Provides the 879N force at 0.7 MPa needed to push packages smoothly across sorting conveyor belts.
Clamping Fixtures
Holds metal or wood components securely in place during light machining and drilling operations.
Gate Operation
Actuates security gates and access barriers where a corrosion-resistant SUS304 rod is beneficial.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX110 the Right Cylinder?
Choose this 40mm bore when a 32mm cylinder (providing 402N push at 0.5 MPa) lacks the necessary thrust, but you want to avoid stepping up to the larger 50mm bore. The 110mm stroke provides a moderate extension length for standard machine cycles.
Because the standard SAI design relies on air pressure for movement, it will not hold a load if supply pressure drops; for fail-safe holding, consider the SAIL locking variant. As a true ISO 15552 profile cylinder, it serves as a direct replacement matching the 40mm bore, 110mm stroke, PT port, and standard mounting accessories like FA flanges.
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 SAI40BX110 FAQ
