About the Airtac SAI100 Standard Air Cylinder SAI100AX40S
The AirTAC SAI100X40-S is a double-acting ISO 15552 profile cylinder engineered for high-force tasks in compact spaces. It generates 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa, making it well-suited for short 40 mm stroke operations requiring immediate power. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a -S magnet for seamless integration with CMSE and DMSE sensor switches, which ride neatly in the dual side grooves. Furthermore, the piston rod is constructed from SUS420J2 stainless steel (material code A), offering enhanced resistance to corrosion and moisture compared to standard carbon steel rods. Fluid must be filtered to 40 um, and the PT threaded G1/2 port ensures reliable pneumatic connectivity.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX40S Is Used
Heavy-Duty Stamping
Applies 5497 N of force at 0.7 MPa to execute short 40 mm stamping and marking operations on metal components.
Pallet Halting
Deploys rapidly to stop heavy pallets on a conveyor line, using the integrated magnet for precise end-of-stroke position confirmation.
Industrial Clamping
Secures large workpieces inside machining centers, leveraging the SUS420J2 stainless steel rod to resist coolant and moisture.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX40S the Right Cylinder?
Select this 100 mm bore model when an application demands substantially more thrust than a 80 mm bore can provide, jumping from 2513 N to 3927 N at 0.5 MPa. The 40 mm stroke is optimal for brief, powerful movements like clamping or pressing. Because the stroke is short, rod-bearing bending is not a concern here, eliminating the need for external guides.
If the machinery requires the load to remain securely in place during a complete loss of air pressure, a standard SAI cylinder will drift. For those safety-critical setups, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. For straightforward actuation, this SAI100X40-S is fully interchangeable with other ISO 15552 cylinders via standard FA, FB, or TC mounting accessories.

- ✓ 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 SAI100 Standard Air Cylinder SAI100AX40S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X40-S is dimensionally interchangeable per ISO 15552. You can drop it into existing foot, flange, or trunnion mounts designed for standard ISO 15552 profile cylinders.
