7312 BECBY Bearing Product Overview & Core Advantages
The 7312 BECBY is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing features a 40° contact angle and P6 (ABEC-3) precision tolerance, making it ideal for applications demanding high rotational accuracy and rigidity. Its optimized internal geometry enables it to accommodate significant radial loads and unidirectional axial loads simultaneously, while the brass cage ensures stable operation at high speeds up to 6,700 rpm. The open design allows for customized lubrication solutions to meet specific operational requirements.

7312 BECBY Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row angular contact design with 40° contact angle provides excellent stiffness against combined loads. With a dynamic load rating of 23,400 lbf and static load rating of 17,212 lbf, this bearing delivers reliable performance in demanding applications.
Precision Engineering: Manufactured to P6 tolerance class (ABEC-3), the bearing ensures minimal runout and vibration. The precise shoulder diameters (outer ring: 104.8mm, inner ring large-side: 87.25mm, small-side: 72.6mm) facilitate accurate positioning and mounting.
High-Speed Capability: The brass cage provides excellent guidance and stability, enabling operation at limiting speeds of 6,700 rpm. The optimized internal geometry reduces friction and heat generation.
Material Quality: Constructed from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and long service life under normal operating conditions.
