About the Airtac SAI40 Standard Air Cylinder SAI40AX90
The AirTAC SAI40X90 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 90mm stroke. It generates 628N of push force at 0.5 MPa and 879N at 0.7 MPa, making it well-suited for medium-duty handling tasks.
This unit is configured with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It uses PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX90 Is Used
Part Ejection
Provides reliable push force to eject finished components from machining centers.
Package Diverting
Actuates diverter arms on packaging lines to route boxes efficiently.
Clamping Fixtures
Secures workpieces in welding or machining fixtures with 879N of force at 0.7 MPa.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX90 the Right Cylinder?
Choose this 40mm bore when an SAI32X90 (402N push at 0.5 MPa) lacks the necessary thrust for your assembly. The 90mm stroke provides ample travel for part ejection or clamping without requiring the full extension of a 100mm or 125mm unit. Because the stroke is under 300mm, side-load stress on the rod bearing is minimal. To mount this cylinder, utilize standard ISO 15552 accessories like FA/FB flanges or LB foot brackets. Note that the standard adjustable air cushions only decelerate the piston near stroke ends; they do not hold a load. If your application requires position holding without air pressure, select the SAIL variant with an air-released 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.
