About the Airtac SAI40 Standard Air Cylinder SAI40BX110S
The AirTAC SAI40X110-S is a double-acting ISO 15552 profile cylinder offering 628N of push force and 528N of pull force at 0.5 MPa. Its 110mm stroke is well-suited for medium-duty positioning tasks on automated lines. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical contamination.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It features PT tapered port threads and is equipped with a magnet (-S) for seamless integration with CMSE or DMSE reed switches via the dual sensor grooves on the barrel.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX110S Is Used
Material Diversion
Actuates routing gates on packaging conveyors where the 628N force easily deflects cartons into secondary processing lanes.
Component Clamping
Secures aluminum housings during CNC machining operations, utilizing the 110mm stroke to clear the work area during part loading.
Press Ejection
Pushes finished stamped parts out of small pneumatic presses, relying on the SUS304 rod to withstand occasional lubricant exposure.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX110S the Right Cylinder?
Choose this 40mm bore when an SAI32 (402N push at 0.5 MPa) lacks the necessary thrust for moving heavier fixtures, but an SAI50 (982N push) would be physically oversized. The 110mm stroke provides a compact extension length for standard machine sequencing. Because it is a double-acting pneumatic actuator, it requires continuous air pressure to hold a load; if your mechanism must resist gravity during a pressure loss, consider the SAIL locking variant or an external pilot check valve.
As a genuine ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders sharing the same 40mm bore, 110mm stroke, PT G1/4 port, and standard mounting accessories like FA flanges or LB foot brackets. The included magnet enables precise end-of-stroke detection without adding external hardware.
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 SAI40BX110S FAQ
At a standard 0.5 MPa operating pressure, this 40mm bore cylinder provides 628N of push force and 528N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 879N.
Yes, the SAI40X110-S is built to the ISO 15552 standard, making it dimensionally interchangeable with other ISO 15552 profile cylinders of the same bore and stroke size.
