7210 BECBPH Bearing Product Overview & Core Advantages
The 7210 BECBPH is a single row angular contact ball bearing designed for high-precision applications requiring exceptional rigidity and high-speed performance. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 40° contact angle optimized for handling significant axial thrust in one direction. Manufactured to P6 (ABEC-3) precision tolerance standards, it delivers reliable operation in demanding industrial environments. Its compact design with a 20mm width makes it ideal for space-constrained applications while maintaining high load capacity.
7210 BECBPH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| BE | High capacity design with optimized internal geometry | Enhanced load rating and extended service life |
| CB | Specific internal clearance and contact angle combination | Optimized for precision applications with controlled preload |
| PH | High-temperature phenolic resin cage material | Superior high-speed performance and thermal stability |
7210 BECBPH 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 9000 lbf while maintaining compact bearing dimensions (50mm bore × 90mm OD × 20mm width).
High-Speed Capability: The phenolic resin (PH) cage provides excellent dimensional stability at high rotational speeds, supporting the limiting speed of 9,000 rpm while reducing friction and heat generation.
Precision Performance: Manufactured to P6 tolerance class with bore diameter tolerance of -0.01mm to 0 and outside diameter tolerance of -0.013mm to 0, ensuring precise shaft positioning and minimal runout in high-precision applications.
Material Excellence: Constructed from chrome steel for both rings and balls, providing superior hardness, wear resistance, and fatigue life. The 40° contact angle delivers optimal axial load capacity while maintaining radial load capability.
