7208 BEGBY Bearing Product Overview & Core Advantages
The 7208 BEGBY is a single row angular contact ball bearing designed for applications requiring high precision and superior performance under combined loads. This metric bearing features a 40mm bore and P6 (ABEC-3) tolerance class, making it ideal for high-speed applications with demanding rigidity requirements. Its optimized 40° contact angle provides excellent capability to handle both radial loads and substantial axial loads in one direction, while the brass cage ensures stable operation at limiting speeds up to 11,000 rpm.
Model Code Detailed Explanation
| Suffix | Technical Meaning | Significance |
|---|---|---|
| BE | Increased internal clearance and contact angle | Optimized for high-speed operation and axial load capacity |
| GB | Special design for combined loads | Enhanced performance under complex loading conditions |
| Y | Brass cage construction | Provides excellent high-speed stability and durability |
7208 BEGBY Bearing Structural Features & Performance Benefits
High Rigidity Design: The single row construction with 40° contact angle and precision-ground raceways delivers exceptional stiffness, making it suitable for applications requiring minimal deflection under load.
Superior Load Capacity: With a radial dynamic load rating of 8,212 lbf and radial static load rating of 5,850 lbf, this bearing efficiently handles combined radial and axial loads in demanding operating conditions.
High-Speed Performance: The brass cage (Y suffix) and optimized internal geometry enable reliable operation at limiting speeds up to 11,000 rpm, while the precise bearing dimensions ensure consistent performance.
Precision Engineering: Manufactured to P6 tolerance class (ABEC-3) with tight dimensional controls, including bore diameter tolerance of -0.01mm to 0, ensuring smooth operation and long service life.
