7002 CDGC/P4A Bearing Product Overview & Core Advantages
The 7002 CDGC/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Operating under the P4A tolerance class, this bearing delivers superior running precision. Its 15° contact angle and Moderate (Class C) preload are optimized to handle combined loads—simultaneously supporting significant radial and axial forces. The Universal Matchable (SU) design allows for precise axial displacement control when mounted in pairs, making it an ideal solution for high-speed spindles and other high-rigidity precision machinery.
7002 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7002 | Standard bearing series designation with 15mm bore, 32mm OD. |
| CD | Contact angle of 15°. |
| GC | Indicates Moderate preload (Class C) for optimal stiffness and minimal deflection. |
| P4A | Denotes a high-precision tolerance class with extremely tight dimensional and running accuracy limits. |
7002 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and Class C preload provide high system rigidity, effectively managing combined radial and axial loads. With a dynamic load rating of 1170 lbf, it ensures reliable performance under demanding conditions.
- High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, contributing to a high limiting speed of 100,000 rpm. This makes it suitable for very high-speed applications.
- Precision Engineering: Manufactured to P4A tolerance standards, this bearing guarantees minimal runout and vibration, which is critical for maintaining accuracy in precision equipment.
- Material & Lubrication: Constructed from chrome steel for both rings and balls, ensuring high durability and wear resistance. The bearing is pre-lubricated for immediate operation within a temperature range of -30°C to 110°C.
