About the Airtac SAI40 Standard Air Cylinder SAI40AX100S
The AirTAC SAI40X100-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 100mm stroke. It delivers a push force of 628N at 0.5 MPa and 879N at 0.7 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists contamination.
This specific configuration includes a -S magnet for use with CMSE and DMSE sensor switches, utilizing the dual sensor grooves machined directly into the barrel. It is built with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. As a genuine AirTAC component, it ensures reliable, long-lasting automation performance.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX100S Is Used
Parts Ejection
Provides robust 879N push force at 0.7 MPa to reliably eject finished metal or plastic parts from machining centers.
Package Diverting
The 100mm stroke offers precise lateral movement to divert packages of moderate weight along sorting conveyors.
Material Gripping
Actuates medium-sized robotic gripper assemblies where the integrated magnet allows end-of-stroke position verification.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX100S the Right Cylinder?
Selecting this 40mm bore over the smaller 32mm version upgrades your push force at 0.5 MPa from 402N to 628N, while stepping up to the 50mm bore yields 982N. The 100mm stroke is a standard length that avoids the side-load and rod-bearing bending risks associated with strokes over 300mm, though external guides are always recommended if heavy lateral loads are present.
Because it is a double-acting cylinder, the SAI40X100-S relies on continuous air pressure to hold its position; it will drift if pressure is lost. For applications requiring fail-safe load holding, consider the SAIL locking variant or an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, meaning it serves as a direct replacement for other ISO 15552 cylinders with a 40mm bore, 100mm stroke, G1/4 port, and standard mounting accessories like FA flanges or TC trunnions.

- ✓ 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.
