7313 BECCM Bearing Product Overview & Core Advantages
The 7313 angular contact ball bearing is a precision single row bearing engineered for applications requiring high accuracy and reliability. Its defining feature is a 40° contact angle, which enables it to support substantial combined loads—simultaneously handling radial forces and unidirectional axial thrust. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. The open design, combined with a robust brass cage, facilitates high-speed operation up to 8,000 rpm, making it an ideal high-speed bearing solution for demanding industrial environments.
7313 BECCM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7313 | Basic bearing designation indicating a metric series with a 65 mm bore, 140 mm outside diameter, and 33 mm width. |
| No Seal Suffix | The bearing is supplied as Open, allowing for optimal lubrication flow and cooling in high-speed applications. |
| P6 | Indicates a tolerance class equivalent to ABEC-3, ensuring high precision in dimensions and running accuracy. |
| 40° Contact Angle | Specifies the geometry optimized for carrying significant axial loads in one direction. |
7313 BECCM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle and robust construction provides excellent resistance to deformation under load. It offers a high dynamic load rating of 26,100 lbf and a static load rating of 19,462 lbf, making it suitable for applications with significant combined radial and axial loads.
- High-Speed Performance: The lightweight and durable brass cage ensures stable operation and guides the balls effectively, contributing to the high limiting speed of 8,000 rpm.
- Precision Engineering: Manufactured to P6 tolerance class with precise bearing dimensions (bore, OD, width) and controlled chamfers, ensuring predictable performance and easy integration into high-precision assemblies.
- Material Quality: Components are made from chrome steel for rings and balls, providing high hardness, wear resistance, and long service life.
