7312 BEGBY Bearing Product Overview & Core Advantages
The 7312 BEGBY is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. This precision bearing features a 40° contact angle, enabling it to support significant radial loads and unidirectional axial loads simultaneously. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and rotational stability. Its optimized internal geometry and brass cage contribute to reliable operation at high speeds up to 6,700 rpm, making it an ideal solution for demanding industrial machinery where high rigidity and operational reliability are paramount.
7312 BEGBY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7312 | Standard bearing series designation indicating a metric single row angular contact bearing with 60mm bore, 130mm OD, and 31mm width. |
| BE | Designates increased internal clearance and optimized internal design for specific preload conditions. |
| GB | Indicates a 40° contact angle, providing enhanced axial load capacity. |
| Y | Specifies a pressed brass cage (sheet metal cage) construction for improved strength and guidance at high speeds. |
7312 BEGBY Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row angular contact design with a 40° contact angle provides excellent stiffness and enables the bearing to handle substantial combined radial and axial loads in one direction. With a dynamic load rating of 23,400 lbf and static load rating of 17,212 lbf, it offers reliable performance in demanding applications.
High-Speed Performance: The brass cage (Y designation) ensures superior cage stability and guidance, contributing to the bearing's ability to operate at limiting speeds of 6,700 rpm. The optimized internal geometry minimizes friction and heat generation.
Precision Engineering: Manufactured to P6 tolerance class (equivalent to ABEC-3), this bearing guarantees precise running accuracy and minimal vibration, essential for high-precision spindle applications.
Material Quality: Constructed from chrome steel for both rings and balls, the bearing delivers excellent durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
