7313 BEGBY Bearing Product Overview & Core Advantages
The 7313 BEGBY is a high-precision single row angular contact ball bearing engineered for demanding applications requiring exceptional rigidity and accuracy. Designed to accommodate combined loads (radial and axial loads in one direction), this bearing features a 40° contact angle that provides superior axial load capacity. Manufactured to P6 (ABEC-3) tolerance class, it delivers reliable performance in high-speed applications with a limiting speed of 6,300 rpm. The open design with brass cage ensures optimal performance in precision machinery where controlled lubrication is required.
7313 BEGBY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| BE | Increased internal clearance | Accommodates thermal expansion in high-speed applications |
| GB | 40° contact angle design | Enhanced axial load capacity and rigidity |
| Y | Brass cage construction | Improved high-speed performance and thermal stability |
7313 BEGBY Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The optimized 40° contact angle and precision-ground raceways provide exceptional stiffness, enabling the bearing to handle significant combined loads. With a radial dynamic load rating of 26,100 lbf and radial static load rating of 19,462 lbf, this bearing offers reliable performance under demanding conditions.
High-Speed Performance: The brass cage (Y suffix) ensures stable operation at high rotational speeds up to 6,300 rpm. The increased internal clearance (BE suffix) accommodates thermal expansion during high-speed operation, maintaining optimal performance.
Precision Engineering: Manufactured to P6 tolerance class with precise dimensional control (bore diameter tolerance: -0.012mm to 0), this bearing ensures accurate positioning and smooth operation in precision applications.
Material Quality: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability across the operating temperature range of -30° to 110°C.
