About the Airtac SAI40 Standard Air Cylinder SAI40X110S
The AirTAC SAI40X110-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 110mm stroke. It generates 879 N of push force at 0.7 MPa, making it well-suited for mid-range industrial actuation tasks.
This variant includes a standard carbon steel piston rod and a built-in magnet (-S) for proximity sensing. The extruded aluminum barrel features sensor grooves on both sides for direct CMSE or DMSE switch mounting, and the fluid port utilizes a PT tapered thread.

Is the Airtac SAI40 Standard Air Cylinder SAI40X110S the Right Cylinder?
If your application requires less force, the 32mm bore offers 563 N at 0.7 MPa, while stepping up to the 50mm bore yields 1374 N for heavier loads. Because this 110mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer extensions.
For drop-in compatibility, match the 40mm bore, 110mm stroke, PT G1/4 port, and your required mounting accessory (such as an FA flange or LB foot). Remember that standard double-acting cylinders drift when air pressure is removed; if your system needs to hold a load safely without live pressure, consider the SAIL locking variant or an external rod lock.
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 SAI40X110S FAQ
At an operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X110-S is dimensionally interchangeable per ISO 15552 profile standards. You can drop it in to replace other ISO 15552 cylinders with a 40mm bore and 110mm stroke, provided you match the PT port and mounting interface.
