2203 ETN9/W64F Bearing Structural Features & Performance Benefits
Double Row Design: The bearing's double row construction provides high rigidity and enables it to handle significant radial loads (2385 lbf dynamic rating) while accommodating axial loads in both directions. This makes it suitable for applications with combined loading conditions.
High-Speed Capability: The TN9 nylon cage ensures excellent performance at high rotational speeds, contributing to the bearing's impressive limiting speed of 24,000 rpm. The cage design reduces friction and heat generation, enhancing overall efficiency.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.008mm to 0, OD: -0.011mm to 0) and CN radial internal clearance, this bearing delivers precise rotational accuracy and smooth operation essential for precision applications.
Material Quality: Constructed from chrome steel for both rings and balls, the bearing offers excellent durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
