7006 CD/HCP4ADBA Bearing Product Overview & Core Advantages
The 7006 CD/HCP4ADBA is a high-precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement provides superior stability and is preloaded to Extra Light (Class A) specifications, ensuring minimal axial and radial runout. Its construction with a phenolic cage and ceramic balls enables outstanding high-speed performance, while the P4A tolerance class guarantees ultra-precise operation. This bearing is engineered to handle combined loads efficiently, making it ideal for high-rigidity, high-speed spindle systems.
7006 CD/HCP4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 26mm width). |
| C | 15° contact angle, optimized for high-speed applications and moderate axial loads. |
| D | Duplex (two bearings as a set). |
| HC | Hybrid Ceramic: Features ceramic balls for reduced weight, lower friction, and higher speed capability. |
| P4A | Ultra-precision tolerance class, exceeding ABEC 7 standards, for applications requiring extreme running accuracy. |
| DB | Back-to-Back mounting arrangement. Provides high moment rigidity and stable load distribution. |
| A | Specific preload grade: Extra light (Class A) preload for minimal friction and heat generation at high speeds. |
7006 CD/HCP4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) design creates a wide, rigid support system that effectively resists moment loads and shaft deflection, ensuring exceptional positional accuracy.
- Superior High-Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage significantly lowers rotational inertia and friction, enabling a high limiting speed of 71,500 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, this bearing delivers ultra-precise rotation essential for high-end machinery.
- Optimized Load Capacity: The 15° contact angle is ideal for handling combined radial and axial loads simultaneously, providing a robust dynamic load rating of 5265 lbf.
- Pre-Lubricated for Immediate Use: The bearing comes lubricated from the factory, ready for installation and initial operation within its specified temperature range of -30°C to 110°C.
7006 CD/HCP4ADBA Bearing Typical Application Areas
