About the Airtac SAI40 Standard Air Cylinder SAI40AX65
The AirTAC SAI40X65 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. Its 65 mm stroke provides a compact extension distance suited for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid ports utilize a PT tapered thread type, and because no magnet is specified, it operates without integrated position sensing.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX65 Is Used
Parts Ejection
Provides the 628 N push force required to positively eject machined components from a fixture in automated machining centers.
Package Diverting
Actuates a diverting arm on a packaging line, using the 65 mm stroke to push cartons onto adjacent handling lanes quickly.
Clamping Fixtures
Secures workpieces during light assembly or welding operations, taking advantage of the SUS420J2 stainless steel rod to resist surface degradation.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX65 the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm bore class, which offers 402 N of push force at 0.5 MPa, to handle heavier actuation loads. The 65 mm stroke is optimal for parts ejection or clamping that needs moderate travel without occupying excessive space. If your mechanism must maintain its position during a loss of air pressure, a standard SAI will drift; you should specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
To match this exact form factor, specify a 40 mm bore, 65 mm stroke, PT port thread, and your required mounting accessory such as an LB foot or FA flange. Because a magnet is omitted, external reed or solid-state sensors cannot be used.
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 SAI40AX65 FAQ
At an operating pressure of 0.5 MPa, this double-acting cylinder generates 628 N of push force and 528 N of pull force. If pressure increases to 0.7 MPa, the push force rises to 879 N.
Yes, the SAI40X65 is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders, provided your mounting interface and port thread match.
