F9-17 Bearing Structural Features & Performance Benefits
Precision Engineering: The F9-17 features flat raceway washers and 10 precision chrome steel balls with a diameter of 3.175mm, ensuring smooth operation and consistent load distribution. The brass cage provides excellent guidance and stability at high rotational speeds.
Load Capacity: With an axial dynamic load rating of 130 lbf and axial static load rating of 141 lbf, this bearing delivers reliable performance in demanding thrust applications. The optimized ball quantity and diameter maximize load-carrying capacity within the compact 5mm width.
High-Speed Capability: The combination of brass cage construction and open design enables operation at limiting speeds up to 8,000 rpm, making it suitable for high-speed applications requiring precise axial positioning.
Material Excellence: Constructed entirely from chrome steel for both rings and balls, the F9-17 offers superior hardness, wear resistance, and dimensional stability across the operating temperature range of -30°C to 110°C.
