7002 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7002 CD/P4ADGC is a precision angular contact ball bearing designed for high-performance applications. Engineered to a P4A tolerance class, it delivers exceptional running accuracy and dimensional stability. Its key advantage lies in its ability to handle combined loads (radial and axial) simultaneously, making it ideal for machine tool spindles and other high-precision machinery. The universal matchable (SU) design allows for flexible mounting arrangements in pairs to support complex load conditions with high rigidity and operational reliability.
7002 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Contact angle of 15° and universal matchable design |
| P4A | High precision tolerance class with enhanced dimensional accuracy |
| DGC | Moderate preload (Class C) for optimal stiffness and reduced vibration |
7002 CD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with a 15° contact angle provides superior stiffness, enabling the bearing to effectively handle combined radial and axial loads. The universal matchable (SU) characteristic allows two bearings to be paired in various configurations (back-to-back, face-to-face, or tandem) to optimize load distribution and system rigidity.
Precision Performance: Manufactured to P4A tolerance class, this bearing ensures minimal runout and exceptional rotational accuracy, which is critical for high-speed applications up to 100,000 rpm. The phenolic cage contributes to smooth operation at high speeds with reduced friction.
Durability & Reliability: Constructed from chrome steel for both rings and balls, the bearing offers excellent wear resistance and long service life. The moderate preload (Class C) minimizes deflection under load, enhancing positioning accuracy and system stability.
