About the Airtac SAI40 Standard Air Cylinder SAI40AX85S
The AirTAC SAI40X85-S is a double-acting ISO 15552 profile cylinder featuring an 85mm stroke and a 40mm bore. It generates 628N of push force and 528N of pull force at 0.5MPa, making it well-suited for mid-range actuation tasks. The extruded aluminum barrel design eliminates protruding tie rods for a clean exterior.
This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance in humid environments. Equipped with a magnet (-S), it supports CMSE and DMSE sensor switches via the integrated dual-side grooves. The pneumatic ports use a PT tapered thread type, and adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX85S Is Used
Automated Clamping
Provides 628N of push force at 0.5MPa to securely hold medium-weight workpieces during machining or welding operations.
Package Diverting
Uses the 85mm stroke to actuate sorting arms and pusher gates on high-speed packaging and material handling lines.
Gate Control
Drives lightweight safety guards and process access doors, benefiting from the SUS420J2 rod's resistance to industrial moisture.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX85S the Right Cylinder?
This 40mm bore provides 628N of push force at 0.5MPa; step down to a 32mm bore (402N push) for lighter loads or up to a 50mm bore (982N push) for heavier demands. As a true ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders, matching standard mounting dimensions for LB, FA, and TC accessories.
If your application requires the load to be held securely without live air pressure, note that the standard adjustable cushion only decelerates the piston and does not act as a brake. For fail-safe holding, consider the SAIL (air-released lock) variant or an external rod lock.
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 SAI40AX85S FAQ
At 0.5MPa, the SAI40X85-S generates 628N of push force and 528N of pull force. At 0.7MPa, the push force increases to 879N.
Yes, the -S suffix indicates this model includes a magnet. It works directly with CMSE and DMSE sensor switches fitted into the dual-side grooves on the extruded aluminum barrel.
