7313 BECBPH Bearing Product Overview & Core Advantages
The 7313 BECBPH is a single row angular contact ball bearing engineered for precision applications requiring high reliability and superior performance. This bearing excels at handling combined loads, accommodating both radial forces and substantial axial loads in one direction. With its 40° contact angle and P6 (ABEC-3) tolerance class, it delivers exceptional rotational accuracy and operational stability. The optimized internal geometry and nylon cage contribute to its capability as a high-speed bearing, making it ideal for demanding industrial environments where precision and durability are paramount.
7313 BECBPH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Impact |
|---|---|---|
| BE | High capacity design with optimized internal geometry | Enhanced load carrying capacity and fatigue life |
| CB | Specific internal clearance and contact angle combination | Optimized for precision applications with controlled preload |
| PH | High temperature phenolic resin cage (equivalent to nylon) | Enables high-speed operation with reduced friction |
7313 BECBPH Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The BE designation indicates enhanced ball complement and raceway design, significantly increasing the radial dynamic load rating to 26,100 lbf and static capacity to 19,462 lbf.
High-Speed Capability: The nylon (PH) cage provides excellent strength-to-weight ratio, reducing centrifugal forces and enabling operation at limiting speeds up to 6,300 rpm.
Precision Performance: Manufactured to P6 (ABEC-3) tolerance class with a 40° contact angle, this bearing ensures minimal runout and superior positioning accuracy for precision machinery.
Thermal Stability: The chrome steel construction maintains dimensional stability across the operating temperature range of -30°C to 110°C, ensuring reliable performance in varied thermal conditions.
