7002 CDGA/P4A Bearing Product Overview & Core Advantages
The 7002 CDGA/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and performance. Engineered with an Extra light (Class A) preload and manufactured to P4A tolerance class, this bearing delivers superior running accuracy, high rigidity, and smooth operation. Its 15° contact angle is optimized to handle combined loads, efficiently supporting both radial and axial forces. The phenolic cage and universal matching designation (SU) make it an ideal choice for high-speed spindle arrangements and other precision machinery where reliability is critical.
7002 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7002 | Basic bearing series, indicating a 15mm bore, 32mm OD, and 9mm width. |
| C | 15° nominal contact angle. |
| DG | Universal Matchable (SU) bearing. Two bearings can be paired in a back-to-back (DB) or face-to-face (DF) arrangement. |
| A | Extra light preload (Class A). |
| P4A | High precision tolerance class, superior to ABEC 7. |
7002 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4A tolerance standards with an extra light preload, this bearing ensures minimal runout and high system stiffness, which is critical for high-speed applications.
- Superior Load Capacity: The 15° contact angle allows the bearing to effectively support combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributes to lower vibration, and enables a high limiting speed of 100,000 rpm. The open design allows for efficient lubrication management.
- Universal Matching Capability (SU): As a universal matchable bearing, two 7002 CDGA/P4A units can be precisely paired to form a pre-loaded set, simplifying installation and ensuring optimal performance in duplex arrangements.
7002 CDGA/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for:
- Machine Tool Spindles
- High-Speed Machining Centers
- Precision Grinding Spindles
- High-Frequency Motors
- Other equipment requiring high rigidity, high speed, and extreme accuracy.
