About the Airtac SAI40 Standard Air Cylinder SAI40AX5
The AirTAC SAI40X5 is a double-acting ISO 15552 profile cylinder offering a 5mm stroke. It provides a push force of 628N and a pull force of 528N at 0.5 MPa, making it ideal for short clamping and ejection tasks.
This specific configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance. It uses PT tapered port threads and lacks a magnet, meaning it cannot directly mount CMSE or DMSE sensors.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX5 Is Used
Short Stroke Clamping
Ideal for holding parts securely in a machining fixture using its 628N push force without requiring long travel.
Product Ejection
Delivers rapid, short-distance ejection of finished components from a conveyor line to a packaging chute.
Valve Actuation
Provides reliable mechanical shifting for diverter valves where a brief, 5mm physical movement is required.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX5 the Right Cylinder?
Choose this 40mm bore when a 32mm cylinder (402N push at 0.5 MPa) lacks the necessary power for brief holding or pressing. The 5mm stroke is optimal for micro-movements where a full extension would waste cycle time. Because the standard SAI does not lock its position upon air loss, incorporate an external check valve if you need to prevent drift. This unit's PT ports and ISO 15552 mounting interface ensure straightforward interchangeability with other standard profile cylinders.

- ✓ 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 SAI40AX5 FAQ
At 0.5 MPa operating pressure, the SAI40X5 generates a push force of 628N and a pull force of 528N. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X5 is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders, matching the 40mm bore, 5mm stroke, and PT porting.
