7308 BECAP Bearing Product Overview & Core Advantages
The 7308 single row angular contact ball bearing is a precision bearing engineered for applications requiring high accuracy and reliable performance under combined loads. Its design is optimized to support significant axial loads in one direction in addition to radial loads, making it ideal for high-speed operations. Manufactured to a P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy. The bearing comes pre-lubricated for immediate use and features a lightweight Nylon cage for superior high-speed capability and smooth operation.
7308 BECAP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 73 | Series designation indicating specific internal geometry and load capacity. |
| 08 | Bore diameter code for a 40 mm bore. |
| No Seal Suffix | The bearing is an open type, allowing for customized lubrication regimes but requiring a clean operating environment. |
| No Cage Suffix | Standard configuration includes a Nylon cage, which is standard for this series and provides excellent high-speed performance and low friction. |
7308 BECAP Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is engineered to handle high radial loads and substantial one-direction axial loads simultaneously. This makes the bearing exceptionally rigid, minimizing deflection under combined loads.
- Optimized for High Speeds: The lightweight Nylon cage reduces centrifugal forces, contributing to a high limiting speed of 10,000 rpm. The optimized internal geometry further enhances its high-speed rotational accuracy.
- Precision Performance: Manufactured to P6 (ABEC-3) tolerance standards, this bearing guarantees precise shaft running and low vibration, which is critical for precision machinery.
- Material Integrity: Constructed from Chrome Steel for both rings and balls, the bearing offers high durability, wear resistance, and a long operational life.
