About the Airtac SAI63 Standard Cylinder SAI63BX290
The AirTAC SAI63X290 is a double-acting ISO 15552 profile cylinder offering 1559 N of push force at 0.5 MPa. With a 290 mm stroke, it provides the extended travel needed for mid-range automation tasks while maintaining a standardized mounting interface.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for easy position detection when required.

Where the Airtac SAI63 Standard Cylinder SAI63BX290 Is Used
Material Diverting
Extends 290 mm to push packages off a main conveyor belt with 1559 N of force at 0.5 MPa.
Press Assembly
Drives medium-duty press operations and component seating tasks requiring reliable linear motion.
Pallet Handling
Positions and pushes pallets or heavy totes during automated storage and retrieval processes.
Is the Airtac SAI63 Standard Cylinder SAI63BX290 the Right Cylinder?
If you need less force, the 50 mm bore provides 982 N at 0.5 MPa, while the 80 mm bore steps up to 2513 N for heavier loads. For this 290 mm stroke, managing side load is critical to prevent rod-bearing bending; utilizing an external guide rail or a fully guided cylinder is strongly recommended.
This SAI63X290 is dimensionally interchangeable per ISO 15552, matching a 63 mm bore, 290 mm stroke, G3/8 PT port, and standard mounting accessories. Note that this cylinder will drift if air pressure is lost; use the SAIL variant or an external pilot-operated check valve if your application requires position holding.
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.
