7007 CB/HCP4A Bearing Product Overview & Core Advantages
The 7007 CB/HCP4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its defining feature is the 15° contact angle and ceramic ball construction, enabling superior performance under combined radial and axial loads. Manufactured to P4 (ABEC-7) tolerance and preloaded, it delivers exceptional running accuracy, rigidity, and rotational stability, making it ideal for demanding, high-reliability machinery.
7007 CB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CB | Specific internal clearance and preload class | Optimized for high rigidity and precise rotational performance. |
| HC | Hybrid Ceramic (Ceramic balls with steel rings) | Reduced weight, lower friction, and extended service life at high speeds. |
| P4A | P4 (ABEC-7) tolerance class with specific accuracy enhancements | Guarantees ultra-high running accuracy and minimal vibration for precision applications. |
7007 CB/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and provides electrical insulation, enabling a limiting speed of 60,000 rpm.
- Phenolic Resin Cage: The lightweight and robust cage material ensures excellent guidance and stability at ultra-high speeds, contributing to the bearing's overall high-speed performance.
- Precision & Preload: Manufactured to P4 tolerance and supplied with a controlled preload, this bearing offers superior axial and radial rigidity, minimizing deflection under load for enhanced machining or positioning accuracy.
- Optimized Internal Geometry: The 15° contact angle is ideal for applications requiring high-speed operation with significant axial load capacity, providing an excellent balance between speed and thrust load handling.
