7015 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7015 CD/P4ADGB is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a light preload (Class B) configuration, it delivers optimal performance in paired arrangements without requiring selective mounting. Its 15° contact angle provides excellent capability for handling combined loads, making it ideal for high-speed, high-rigidity applications where precise axial and radial positioning is critical.

| CD | 15° contact angle, universal matchable design | Optimized for combined radial and axial loads, interchangeable mounting |
| P4A | ABEC 7/P4 precision class with enhanced running accuracy | Superior rotational precision and minimal vibration |
| DGB | Light preload (Class B), universal matching pair | Reduced deflection, improved stiffness, simplified installation |
7015 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The angular contact design with 15° contact angle and light preload ensures exceptional system stiffness and minimal deflection under load. The P4A tolerance class guarantees superior running accuracy for precision applications.
Optimized Load Capacity: With a radial dynamic load rating of 19,170 lbf and radial static load rating of 22,050 lbf, this bearing efficiently handles combined loads while maintaining precision. The universal matchable design allows for flexible mounting configurations in duplex arrangements.
High-Speed Performance: The phenolic cage and optimized internal geometry contribute to stable operation at high speeds, with a limiting speed of 22,000 rpm. The open design facilitates efficient lubrication management for thermal stability.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, the bearing delivers excellent durability and wear resistance. The phenolic cage provides superior strength and reduced friction at high speeds.
