7006 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7006 CD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing is universally matchable (SU), allowing two bearings to be paired in a back-to-back (DB), face-to-face (DF), or tandem (DT) arrangement to optimize performance for specific load conditions. Its 15° contact angle and moderate preload (Class C) provide superior high-speed capability and stability, making it ideal for supporting combined loads (radial and axial) simultaneously in high-precision machinery.
7006 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 26mm width). |
| CD | Specifies a 15° contact angle and a specific internal design optimized for high rigidity. |
| P4A | Indicates a super-precision tolerance class, with enhanced running accuracy for the inner and outer rings. |
| DGC | Denotes a universally matchable (SU) bearing, supplied lubricated and with a phenolic cage. |
7006 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and moderate preload provide high system stiffness, enabling the bearing to effectively handle combined radial and axial loads.
- Superior High-Speed Performance: The lightweight phenolic cage, precision-ground chrome steel components, and optimized 15° contact angle collectively contribute to a high limiting speed of 100,500 rpm.
- Precision Engineering: Manufactured to P4A tolerance standards, this bearing ensures minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
- Universal Matchability (SU): This feature allows for flexible arrangement of two bearings to create a pre-loaded set, significantly enhancing operational stability and load-sharing capabilities.
7006 CD/P4ADGC Bearing Typical Application Areas
This bearing is ideally suited for high-precision, high-speed applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Equipment
- Industrial Pumps and Compressors
- Aerospace Control Systems
