7313 BEGBM Bearing Product Overview & Core Advantages
The 7313 BEGBM is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Its design is optimized to simultaneously support significant radial loads and one-direction axial loads, making it an ideal choice for applications demanding high rigidity and operational accuracy. Manufactured to a P6 (ABEC-3) tolerance class and featuring a robust brass cage, this bearing ensures reliable performance in demanding environments. The standard 40° contact angle provides excellent axial load capacity, while its open design allows for versatile lubrication options to suit specific operational needs.
7313 BEGBM Bearing Model Code Explained, Specifications & Naming Convention

|---|---|
| 7313 | Basic bearing series number, indicating a metric series with a 65 mm bore and 140 mm outside diameter. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| G | Indicates a brass cage, providing high strength and excellent guidance at high speeds. |
| BM | Signifies that the bearing is supplied lubricated. |
7313 BEGBM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design, combined with a 40° contact angle and high-quality chrome steel rings and balls, provides exceptional resistance to deformation under combined radial and axial loads. The robust construction ensures stable operation and long service life.
- Precision and High-Speed Capability: Manufactured to P6 (ABEC-3) tolerance standards, this bearing guarantees running accuracy. The brass cage (G) is engineered for stability and reduced friction, contributing to a high limiting speed of 8,000 rpm.
- Optimized Internal Geometry: Critical dimensions such as the shoulder diameters (inner ring: 94.15 mm / 78.45 mm, outer ring: 112.85 mm) and the 60 mm distance to the load point are precisely controlled to ensure optimal load distribution and alignment in the application.
- Versatile Lubrication and Temperature Range: The open seal type allows for easy re-lubrication and the use of specialized greases. The bearing operates effectively within a temperature range of -30°C to 110°C.
