7310 BECBP Bearing Product Overview & Core Advantages
The 7310 BECBP is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Featuring a 40° contact angle and P6 (ABEC-3) precision tolerance, this bearing is optimized to handle significant axial loads in one direction while supporting radial loads. Its nylon cage construction and pre-lubrication enable smooth operation at high speeds up to 8,000 rpm, making it an ideal solution for applications demanding high rigidity and operational accuracy.
7310 BECBP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| BE | High capacity design with optimized internal geometry | Enhanced load carrying capacity and longer service life |
| CB | Specific internal clearance and contact angle combination | Optimized for precision applications with controlled preload |
| P | Glass fiber reinforced nylon cage | Excellent high-speed performance with reduced friction |
7310 BECBP Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The BE design features enhanced raceway curvature and ball complement, significantly increasing the dynamic load rating to 16,875 lbf while maintaining compact bearing dimensions (50mm bore × 110mm OD × 27mm width).
Precision Engineering: Manufactured to P6 tolerance class with bore diameter tolerance of -0.01mm to 0, ensuring precise shaft fitment and minimal runout for high-precision applications.
High-Speed Capability: The nylon cage provides excellent strength-to-weight ratio, enabling stable operation at the limiting speed of 8,000 rpm while reducing centrifugal forces and heat generation.
Angular Contact Design: With a 40° contact angle and optimized shoulder diameters (inner ring: 73.8mm large-side, 61.13mm small-side), this bearing delivers superior axial load capacity in one direction while maintaining excellent radial load performance.
