About the Airtac SAI40 Standard Air Cylinder SAI40AX290S
The AirTAC SAI40X290-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting interchangeability. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force, making it well-suited for mid-range automation tasks requiring a 290 mm stroke.
Built with a SUS420J2 stainless steel rod (option A), this model offers superior corrosion resistance compared to standard carbon steel. The -S suffix indicates an integrated magnet for direct mounting of CMSE or DMSE series sensor switches along the extruded aluminum barrel's dual grooves.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX290S Is Used
Package Diverting
Extends 290 mm to push medium-weight cartons smoothly across sorting conveyor belts in logistics hubs.
Component Insertion
Presses lightweight bearings or pins into housings on automated assembly lines using 879 N of push force at 0.7 MPa.
Pallet Positioning
Stops or aligns empty pallets at wrapping stations, utilizing the dual sensor grooves for precise end-position feedback.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX290S the Right Cylinder?
If your application requires less force, stepping down to a 32 mm bore yields 402 N of push force at 0.5 MPa, while stepping up to a 50 mm bore provides 982 N for heavier loads. The 290 mm stroke falls within the standard 1200 mm maximum for this bore, but strokes of 300 mm or more require careful side-load management to prevent rod-bearing bending; utilizing an external guide rail or a fully guided cylinder is strongly recommended for long unsupported rods.
This configuration features a PT tapered G1/4 port and includes a magnet for position sensing. Because it is a standard double-acting cylinder, it will not hold a load if air pressure is lost or exhausted; for positive holding without live pressure, consider the SAIL locking 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 SAI40AX290S FAQ
