| Y | Indicates special tolerances or performance characteristics as defined by manufacturer standards |
7313 BECBY Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated raceway geometry deliver superior axial load capacity while maintaining excellent radial load performance. This design ensures stable operation under combined loading conditions.
High-Speed Capability: Featuring a brass cage that provides excellent strength and wear resistance at high rotational speeds, contributing to the bearing's limiting speed of 6,300 rpm. The optimized internal design minimizes friction and heat generation.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional control on bore diameter (-0.012mm to 0), outside diameter (-0.015mm to 0), and width (-0.05mm to 0) for consistent performance in precision applications.
Robust Construction: Both rings and balls are made from chrome steel, providing high hardness, wear resistance, and durability. The open design allows for efficient lubrication management in various operating conditions.
