7330 BCBM Bearing Product Overview & Core Advantages
The 7330 BCBM is a single row angular contact ball bearing engineered for applications requiring exceptional precision and reliability. This metric bearing features a P6 tolerance class (ABEC-3), ensuring high running accuracy. Its defining characteristic is the 40° contact angle, which is optimized to support significant combined loads—handling both high radial loads and unidirectional axial loads simultaneously. The open design allows for versatile lubrication options, making it suitable for high-speed operation up to 2,800 rpm. Constructed from chrome steel with a brass cage, it offers excellent durability and stable performance in demanding environments.
7330 BCBM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Significance |
|---|---|---|
| BCBM | Bearing with specific internal design and contact angle | Indicates a 40° contact angle and optimized internal geometry for high axial load capacity and rigidity. |
| Open (No Seal Suffix) | No integral seals or shields | Enables high-speed performance and allows for custom lubrication systems to be implemented. |
7330 BCBM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle provides superior rigidity and is specifically engineered to handle heavy combined radial and axial loads in one direction efficiently.
- Precision & High-Speed Performance: Manufactured to a P6 tolerance class and featuring a robust brass cage, this bearing ensures smooth operation and stability at limiting speeds up to 2,800 rpm.
- Optimized Internal Geometry: Critical dimensions such as the shoulder diameters (Inner ring large-side: 216.1 mm, Outer ring: 258.65 mm) and a distance to load point of 131 mm are precision-machined to ensure optimal load distribution and moment load resistance.
- Material & Compliance: Components made from high-grade chrome steel offer excellent wear resistance and fatigue life. The bearing is ROHS and REACH compliant, meeting stringent environmental regulations.
