7015 CD/HCP4A Bearing Product Overview & Core Advantages
The 7015 CD/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and rigidity. This single-row bearing features a 15° contact angle and is supplied with a preload, making it ideal for setups where minimal axial and radial deflection under load is critical. Its construction with a phenolic cage and ceramic balls contributes to lower friction, higher limiting speed, and superior performance in high-speed operations. This bearing is designed to handle combined loads, primarily thrust loads in one direction, with high reliability.
7015 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7015 | Basic bearing series, indicating a metric bore diameter of 75mm and outside diameter of 115mm. |
| CD | A matched arrangement designation, indicating a specific internal clearance and preload for optimized performance in duplex pairs. |
| HC | Refers to the Hybrid Ceramic construction, featuring ceramic balls and steel rings for enhanced speed and durability. |
| P4 | The tolerance class, equivalent to ABEC-7, denoting very high precision in dimensional and running accuracy. |
| A | Indicates a 30° contact angle. (Note: Specification lists 15°, please verify model code consistency for application). |
7015 CD/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: Manufactured to a P4 (ABEC-7) tolerance class, this bearing ensures extremely tight dimensional control, resulting in superior running accuracy and system high rigidity.
Enhanced High-Speed Capability: The combination of a lightweight phenolic cage and low-density ceramic balls reduces centrifugal forces, enabling a high limiting speed of 22,000 rpm. This hybrid ceramic design also minimizes heat generation.
Superior Load Capacity: With a radial dynamic load rating of 11,858 lbf and a radial static load rating of 11,025 lbf, it is built to handle significant combined loads.
Optimized for Preload: The bearing is supplied with a preload, which increases system stiffness, reduces vibration, and improves positional accuracy in the application.
