7006 CD/HCP4ADBC Bearing Product Overview & Core Advantages
The 7006 CD/HCP4ADBC is a precision duplex angular contact ball bearing designed for applications requiring exceptional rigidity and high-speed performance. This matched back-to-back (DB) arrangement is preloaded to provide superior stability and can simultaneously support combined radial and axial loads. Manufactured to P4A tolerance class and featuring ceramic balls and a phenolic cage, it delivers high reliability in demanding, high-precision environments.
7006 CD/HCP4ADBC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Duplex bearing with back-to-back (DB) arrangement and moderate preload (Class C) |
| HC | Hybrid Ceramic: Features ceramic balls for reduced friction and higher speed capability |
| P4A | High precision tolerance class exceeding ABEC 7 standards |
| Open | No seals or shields, optimized for high-speed lubrication systems |
7006 CD/HCP4ADBC Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The back-to-back duplex arrangement with moderate preload provides exceptional system stiffness, minimizing deflection under combined loads and moment loads.
- Enhanced Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage enables a high limiting speed of 71,500 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight bore and outside diameter tolerances, ensuring precise running accuracy and minimal vibration.
- Superior Load Capacity: The 15° contact angle and optimized internal geometry provide high dynamic and static load ratings for demanding applications.
