About the Airtac SAI40 Standard Air Cylinder SAI40AX35S
The AirTAC SAI40X35-S is a double-acting ISO 15552 profile cylinder engineered for compact actuation. It delivers 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for short-travel clamping and positioning tasks.
This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance. It is equipped with a PT tapered port thread and features an integrated magnet (-S) that allows direct mounting of CMSE or DMSE series sensor switches along the extruded aluminum barrel grooves.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX35S Is Used
Short-Stroke Clamping
Ideal for holding lightweight workpieces securely during machining or assembly operations.
Package Diverter
Provides rapid, short-travel actuation to push packages off a main conveyor belt at high speeds.
Gate Ejection
Delivers reliable force to eject molded parts or open small process gates in automated machinery.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX35S the Right Cylinder?
If 628N of push force at 0.5 MPa is insufficient for your load, step up to the 50mm bore, which provides 982N. For this 35mm stroke, side load is minimal, but always ensure the rod bearing is aligned with the load center. Being a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders. To match this exact unit, specify a 40mm bore, 35mm stroke, PT G1/4 port, and the -S magnet option.
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 SAI40AX35S FAQ
At an operating pressure of 0.5 MPa, the SAI40X35-S provides a push force of 628N and a pull force of 528N.
No, the standard SAI cylinder does not hold its position when pressure is lost. If you need fail-safe load holding, consider the SAIL (lock) or BSAI (clamp-lock) variants, or use an external rod lock.
