7006 CDGA/HCP4A Bearing Product Overview & Core Advantages
The 7006 CDGA/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Engineered with a 15° contact angle and an Extra Light (Class A) preload, this bearing is optimized for high-speed operation and provides superior rigidity. Its open seal design allows for custom lubrication solutions, while the combination of a ceramic ball and phenolic cage enables outstanding performance with reduced friction and heat generation. As a Universal Matchable (SU) bearing supplied in a set of three, it is ideal for precise, pre-loaded spindle arrangements.
7006 CDGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CDGA | Indicates a 15° contact angle and Extra Light (Class A) preload. This configuration is optimized for high-speed applications requiring minimal friction and high rigidity. |
| HCP4A | Signifies the P4A tolerance class, denoting extremely high dimensional and running accuracy. The "HC" prefix may refer to a specific manufacturer's designation for a high-capacity or hybrid ceramic design. |
7006 CDGA/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The angular contact design with a 15° contact angle and Class A preload provides excellent axial and radial stiffness, ensuring precise shaft positioning and minimal deflection under load.
- Superior High-Speed Capability: The use of ceramic balls significantly reduces centrifugal forces and friction, while the lightweight phenolic cage ensures stability. This combination allows for the high limiting speed of 100,500 rpm.
- Optimized for Matched Sets: As a Universal Matchable (SU) bearing supplied in a set of three, it enables the creation of pre-loaded bearing arrangements (e.g., DB or DF pairs) with optimized internal load distribution for maximum system rigidity and accuracy.
- Wide Temperature Range: The specified materials and pre-lubrication allow for reliable operation within a temperature range of -30°C to 110°C.
7006 CDGA/HCP4A Bearing Typical Application Areas
The 7006 CDGA/HCP4A is engineered for high-performance machinery where precision and speed are critical. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling machines and precision engraving equipment.
- High-Frequency Motors: Spindles for routers and small high-speed motors.
