7311 BEGAM Bearing Product Overview & Core Advantages
The 7311 BEGAM is a single row angular contact ball bearing designed for high-precision applications requiring exceptional performance under combined loads. Engineered with P6 (ABEC-3) precision tolerance and a 40° contact angle, this bearing delivers superior axial load capacity in one direction while maintaining excellent radial load handling. Its open design allows for optimal lubrication management, making it ideal for high-speed operations up to 9,000 rpm. The combination of chrome steel rings, chrome steel balls, and a brass cage ensures high rigidity, extended service life, and reliable operation in demanding industrial environments.

7311 BEGAM Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row angular contact design with 40° contact angle provides exceptional axial load capacity in one direction while effectively handling radial loads. The optimized bearing dimensions and material selection ensure stable operation under combined loads.
Precision Performance: Manufactured to P6 (ABEC-3) tolerance class, this bearing delivers consistent performance in high-precision applications. The precise bore diameter tolerance (-0.012mm to 0) and outside diameter tolerance (-0.013mm to 0) ensure perfect fit and alignment.
High-Speed Capability: With a limiting speed of 9,000 rpm and brass cage construction, the bearing maintains stability and reduced friction at high rotational speeds. The optimized contact angle and lubrication system contribute to smooth high-speed operation.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability. The brass cage offers superior strength and temperature resistance for reliable performance across the operating temperature range of -30° to 110°C.
