7013 CDGC/P4A Bearing Product Overview & Core Advantages
The 7013 CDGC/P4A is a single row angular contact ball bearing engineered for applications demanding high precision and superior running accuracy. Positioned in the P4A tolerance class, it offers exceptional dimensional stability and rotational precision. Its 15° contact angle is optimized to handle significant axial loads in one direction, while also supporting radial loads. The Universal Matchable (SU) design allows for flexible mounting in various preloaded configurations, such as back-to-back or face-to-face, enabling engineers to achieve the exact stiffness and performance characteristics required for high-speed machinery.
7013 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| CD | Moderate Preload (Class C) | Provides optimal bearing stiffness and reduces deflection under load for enhanced operational accuracy. |
| GC | Universal Matchable (SU) Bearing Set | Offers flexibility in mounting arrangements to achieve desired preload and rigidity without selective mounting. |
| P4A | High Precision Tolerance Class | Ensures extremely tight dimensional and running accuracy, crucial for high-speed and precision applications. |
7013 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 15° contact angle and Moderate (C) preload provides high axial and radial stiffness, effectively handling combined loads and minimizing shaft displacement.
- Superior High-Speed Performance: The lightweight phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to the high limiting speed of 24,000 rpm. The bearing is supplied lubricated for immediate operation.
- Precision Engineering: Manufactured to P4A tolerance class with tight bore and outside diameter tolerances, this bearing guarantees exceptional running accuracy and low noise/vibration levels.
- Durable Construction: Components made from chrome steel offer high load ratings (Dynamic: 9360 lbf, Static: 8438 lbf) and excellent wear resistance, ensuring long service life.
