7313 BECBP Bearing Product Overview & Core Advantages
The 7313 BECBP is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing is distinguished by its ability to support significant radial loads and unidirectional axial loads simultaneously, thanks to its optimized 40° contact angle. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and rotational stability. The bearing comes pre-lubricated and features a lightweight nylon cage, making it an ideal solution for high-speed operation up to 6,300 rpm while maintaining operational reliability.
7313 BECBP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| BE | Increased internal clearance and optimized internal geometry | Enhanced performance under thermal expansion and preload conditions |
| CB | Specific internal clearance and contact angle combination | Optimized for combined load capacity and high-speed operation |
| P | P6 tolerance class (equivalent to ABEC-3) | Superior running accuracy and dimensional precision |
7313 BECBP Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 7313 BECBP features a 40° contact angle that provides excellent axial load capacity while maintaining substantial radial load capability. The calculated distance from side face to load point (60 mm) ensures optimal moment load distribution.
High-Speed Capability: The nylon cage construction reduces rotational mass and friction, enabling limiting speeds of 6,300 rpm. This makes the bearing suitable for demanding high-speed applications where thermal stability is critical.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional controls (bore diameter tolerance: -0.012mm to 0, outside diameter tolerance: -0.015mm to 0), this bearing ensures consistent performance in precision machinery.
Robust Load Capacity: With a dynamic load rating of 26,100 lbf and static load rating of 19,462 lbf, the bearing delivers reliable performance under significant combined loads while maintaining operational integrity.
7313 BECBP Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers requiring accurate rotational performance
- Industrial Pumps: Centrifugal and process pumps operating at medium to high speeds
- Electric Motors: High-performance motors demanding precise bearing alignment
- Gearboxes: Power transmission systems requiring reliable angular contact bearing support
