7006 CDTP/HCP4B Bearing Product Overview & Core Advantages
The 7006 CDTP/HCP4B is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. Its primary advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and axial loads in one direction. Manufactured to a P4 (ABEC-7) tolerance class and featuring a phenolic cage and ceramic balls, this bearing is optimized for high-speed operation up to 38,000 rpm, offering superior rigidity, reduced friction, and extended service life in precision machinery.
7006 CDTP/HCP4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 7006 | Standard series and size designation (30mm bore, 55mm OD) | Defines the core bearing dimensions. |
| C | 15° contact angle | Optimized for high-speed performance and moderate axial load capacity. |
| D | High rigidity internal design | Enhanced structural support for improved stability. |
| T | Phenolic (synthetic resin) cage | Lightweight cage for reduced centrifugal forces, enabling higher limiting speeds. |
| P | Preload applied | Eliminates internal clearance for superior running accuracy and system stiffness. |
| HCP4B | Hybrid Ceramic, P4 Precision, Lubricated | Indicates the use of ceramic balls for lower friction and higher speed, P4 tolerance, and factory-applied lubrication. |
7006 CDTP/HCP4B Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride (Si3N4) ceramic balls significantly reduces friction, heat generation, and wear. This results in higher limiting speeds, longer lubricant life, and improved reliability, especially in high-velocity applications.
- High Rigidity & Running Accuracy: The application of a specific preload ensures zero internal clearance, providing maximum system stiffness and exceptional running accuracy. This is critical for applications where shaft displacement must be minimized.
- Optimized High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, while the 15° contact angle and low-friction ceramic balls work in concert to achieve an impressive limiting speed of 38,000 rpm.
- Superior Load Capacity: Designed as a single, preloaded angular contact bearing, it offers a high dynamic load rating of 3218 lbf, making it capable of handling demanding combined radial and axial loads.
7006 CDTP/HCP4B Bearing Typical Application Areas
This high-performance bearing is ideally suited for precision equipment where speed, accuracy, and rigidity are paramount. Key industries and machinery include:
- High-Frequency Machine Tool Spindles
