About the Airtac SAI63 Standard Cylinder SAI63AX290S
The AirTAC SAI63X290-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force and 1402 N of pull force at 0.5 MPa. Featuring a 63 mm bore and a 290 mm stroke, this unit is built for robust linear motion tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that prevents debris accumulation while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or mildly chemical environments. Equipped with a -S magnet, the barrel integrates dual sensor grooves that seamlessly accept CMSE and DMSE series switches for precise position detection. Fluid connections utilize PT tapered threads, ensuring a reliable, sealed pneumatic interface.

Where the Airtac SAI63 Standard Cylinder SAI63AX290S Is Used
Material Bending Jigs
Provides the 1559 N push force at 0.5 MPa needed to secure and actuate medium-duty bending fixtures, while the SUS420J2 rod resists shop-floor coolant exposure.
Package Diverters
The 290 mm stroke offers ample travel to redirect large cartons on sorting lines, utilizing the integrated -S magnet for end-of-stroke confirmation.
Vertical Lift Gates
Drives access gates and heavy lifting platforms where a true ISO 15552 mounting footprint allows seamless integration into existing conveyor frameworks.
Is the Airtac SAI63 Standard Cylinder SAI63AX290S the Right Cylinder?
Selecting this 63 mm bore is ideal when a 50 mm bore (982 N push at 0.5 MPa) lacks sufficient power, but an 80 mm bore (2513 N push at 0.5 MPa) would be physically oversized. The 290 mm stroke offers extensive travel, but strokes of 300 mm or greater introduce side-load risks that can bend unsupported rods or accelerate rod-bearing wear. For this length, ensure the load is guided externally or utilize a guided cylinder carriage to prevent mechanical deflection.
Because this is a standard double-acting cylinder, it will not maintain its position or hold a load if air pressure is lost or the valve is centered; the piston will drift. If your application requires fail-safe load holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. When replacing an existing ISO 15552 actuator, match the 63 mm bore, 290 mm stroke, G3/8 port, PT thread type, and appropriate mounting accessories like FA flanges or TC trunnions.
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 SAI63 Standard Cylinder SAI63AX290S FAQ
At 0.5 MPa, this cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes. As a profile-type ISO 15552 cylinder, it is dimensionally interchangeable with other standard ISO 15552 cylinders, provided you match the 63 mm bore, 290 mm stroke, and G3/8 port size.
