7208 BECBPH Bearing Product Overview & Core Advantages
The 7208 BECBPH is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance. This metric bearing is characterized by its ability to accommodate combined loads—simultaneously handling significant radial loads and axial loads in one direction. Manufactured to a P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and rotational stability. Its optimized 40° contact angle and nylon cage contribute to its suitability for high-speed operation and low noise levels, making it an ideal component for demanding industrial environments.
7208 BECBPH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| BE | High capacity, increased ball complement and optimized internal geometry. | Enhances load carrying capacity and extends service life. |
| CB | Specific internal clearance and contact angle combination. | Provides optimal preload and stiffness for precision applications. |
| PH | Nylon (Polyamide) cage, snap-type design. | Enables quiet operation and is ideal for high-speed performance. |
7208 BECBPH Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is optimized to support high radial loads and substantial one-direction axial loads. The BE design with an increased ball count further boosts the dynamic and static load ratings (8212 lbf / 5850 lbf).
- High-Speed Performance: The lightweight nylon (PH) cage minimizes centrifugal forces and friction, allowing for a high limiting speed of 11,000 rpm. The open design facilitates efficient lubrication management.
- Precision Engineering: Manufactured to P6 tolerance with strict dimensional control on the bore diameter (40 mm) and outside diameter (80 mm), ensuring predictable performance and ease of installation in precision assemblies.
- Material & Compliance: Constructed from chrome steel for both rings and balls, providing high durability and resistance to wear. The bearing is compliant with ROHS and REACH environmental standards.
