About the Airtac SAI40 Standard Air Cylinder SAI40X100S
The AirTAC SAI40X100-S is a double-acting ISO 15552 profile cylinder offering a 40mm bore and 100mm stroke. It generates 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa, making it well-suited for mid-range industrial pushing and clamping tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a standard carbon steel piston rod and features a built-in magnet (-S) for seamless integration with CMSE and DMSE series sensor switches. The barrel incorporates sensor grooves on both sides for flexible switch mounting. Standard environmental sealing is TPU, but Viton (H) options are available if your application involves elevated operating temperatures.

Where the Airtac SAI40 Standard Air Cylinder SAI40X100S Is Used
Part Ejection
Provides reliable 879 N push force at 0.7 MPa to eject molded parts from machinery quickly.
Package Diverting
The 100mm stroke is optimal for actuating diverter arms on medium-duty packaging conveyors.
Workpiece Clamping
Generates secure holding power for positioning and clamping aluminum or steel workpieces during machining.
Is the Airtac SAI40 Standard Air Cylinder SAI40X100S the Right Cylinder?
Select this 40mm bore when an SAI32X100-S (providing 563 N at 0.7 MPa) lacks the necessary thrust for your fixture. If you need to move a heavier payload, stepping up to the SAI50X100-S yields 1374 N at 0.7 MPa. At a 100mm stroke, the rod bearing handles side loads adequately without requiring external guides.
This model uses a PT tapered G1/4 port and accepts standard FA flange or LB foot mounting accessories. Because it is a standard double-acting cylinder, it will not hold a load if air pressure drops; for position holding 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 SAI40X100S FAQ
At an operating pressure of 0.7 MPa, the SAI40X100-S generates 879 N of push force and 528 N of pull force. At 0.5 MPa, it provides 628 N push and 528 N pull.
Yes, the SAI40X100-S is a genuine ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions allow it to serve as a drop-in replacement for other standard ISO 15552 cylinders.
