About the Airtac SAI40 Standard Air Cylinder SAI40AX40S
The AirTAC SAI40X40-S is a double-acting ISO 15552 profile cylinder engineered for compact, high-cycle operations. Delivering 628 N of push force at 0.5 MPa, this 40 mm bore unit is tailored for short-stroke sequencing. The integrated -S magnet enables direct mounting of CMSE or DMSE sensor switches along the dual-sided extruded aluminum barrel grooves.
Built for demanding environments, the piston rod utilizes SUS420J2 stainless steel for superior corrosion resistance compared to standard carbon steel. Fluid supply connects via a PT tapered G1/4 port, ensuring a robust, leak-free pneumatic seal.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX40S Is Used
Small Part Ejection
Provides reliable 628 N push force to eject small molded components from machining centers.
Package Diverting
Actuates diverter arms on packaging lines where rapid, short-stroke movements are required.
Clamp Positioning
Moves lightweight clamping fixtures into position using integrated CMSE sensors for confirmation.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX40S the Right Cylinder?
Select this 40 mm bore when an application requires more power than a 32 mm bore (402 N at 0.5 MPa) but maintains a minimal footprint. The 40 mm stroke provides rapid actuation without occupying excessive axial space. For interchangeability, this model aligns with ISO 15552 mounting interfaces, accepting standard FA/FB flanges or LB foot brackets.
If the machinery loses air pressure, this standard cylinder cannot sustain a load and the rod will drift. For vertical loads requiring fail-safe holding, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
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 SAI40AX40S FAQ
