7320 BEGAF Bearing Product Overview & Core Advantages
The 7320 BEGAF is a single row angular contact ball bearing designed for applications requiring high precision and exceptional performance under combined loads. This metric bearing features a 40° contact angle optimized for handling significant axial loads in one direction while supporting substantial radial loads. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and rotational precision. The bearing's stainless steel cage ensures reliable operation at high speeds up to 3,600 rpm, while its chrome steel construction provides excellent durability and fatigue resistance in demanding industrial environments.

| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| BE | Increased internal clearance and optimized internal geometry | Enhanced performance under thermal expansion and high-speed conditions |
| GA | Light preload | Improved rigidity and reduced vibration for precision applications |
| F | Filling slot for enhanced lubrication | Extended service life and improved high-temperature performance |
7320 BEGAF Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated raceway curvature provide superior load distribution, enabling the bearing to handle combined radial and axial loads efficiently. The distance from side face to load point of 90 mm ensures optimal moment load capacity.
High-Speed Capability: The stainless steel cage offers excellent strength-to-weight ratio and corrosion resistance, contributing to stable operation at the limiting speed of 3,600 rpm. The open design facilitates efficient lubrication distribution.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional controls (bore tolerance: -0.015mm to 0, OD tolerance: -0.02mm to 0), ensuring consistent performance and easy installation in precision assemblies.
Robust Load Capacity: With dynamic load rating of 45,675 lbf and static load rating of 42,750 lbf, this bearing delivers reliable performance in heavy-duty applications while maintaining dimensional stability.
