7264 BCBM Bearing Product Overview & Core Advantages
The 7264 BCBM is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. Its defining feature is the 40° contact angle, which provides superior axial load capacity in one direction while effectively handling substantial radial loads. Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures high running accuracy and reliability. The combination of a brass cage and optimized internal geometry contributes to stable operation at its specified limiting speed, making it an ideal component for demanding, high-rigidity systems.
7264 BCBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7264 | Standard bearing size designation (320mm bore, 580mm OD, 92mm width). |
| BCBM | Indicates a specific internal design and contact angle (40°) optimized for high axial load capacity. |
7264 BCBM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a steep 40° contact angle is engineered to support high unidirectional axial loads and significant radial loads simultaneously. The calculated distance from side face to load point (236mm) ensures optimal load distribution and moment load resistance.
- Precision & Speed: Built to P6 tolerance for precise shaft guidance and low vibration. The brass cage provides strength and stability, enabling reliable operation up to the specified limiting speed.
- Durability & Compliance: Components are manufactured from chrome steel for high durability and fatigue resistance. The bearing is supplied lubricated and is compliant with ROHS and REACH environmental standards.
7264 BCBM Bearing Typical Application Areas
This bearing is suited for heavy-duty machinery and precision equipment where high axial and radial load capacity is critical. Common applications include:
- Machine Tool Spindles
- Industrial Gearboxes
- Large Pumps and Compressors
- Precision Turntables and Indexing Tables
