About the Airtac SAI40 Standard Air Cylinder SAI40AX90S
The AirTAC SAI40X90-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 90mm stroke. It provides a push force of 628 N at 0.5 MPa, making it well-suited for mid-range industrial handling tasks. The extruded aluminum barrel design omits tie-rods for a clean exterior.
This specific configuration includes an -S magnet for use with CMSE and DMSE sensor switches, which mount directly into the dual side grooves. The piston rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance, and the fluid port utilizes a PT tapered G1/4 thread.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX90S Is Used
Package Diverting
Provides the precise 628 N force and 90mm travel needed to push cartons smoothly across sorting conveyor belts.
Component Clamping
Secures workpieces during light machining or assembly, using the SUS420J2 stainless rod to resist workshop moisture.
Pick and Place
Handles small to medium payloads in automated lines, pairing the internal magnet with DMSE sensors for position verification.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX90S the Right Cylinder?
If your application requires less force, stepping down to the 32mm bore yields 402 N of push force at 0.5 MPa. Conversely, moving up to the 50mm bore provides 982 N. Because this 90mm stroke is relatively short, side-load stress on the rod bearing is minimal, but always ensure axial load alignment.
Being a true ISO 15552 profile cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders. To hold a load safely without continuous air pressure, integrate the SAIL locking variant or an external pilot-operated check valve, as the adjustable air cushions only decelerate the piston near stroke end.
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 SAI40AX90S FAQ
