7006 CEGA/HCP4A Bearing Product Overview & Core Advantages
The 7006 CEGA/HCP4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and performance. Engineered to accommodate combined loads (radial and axial), this bearing features a single-row design with a 15° contact angle, optimized for high-speed operation and superior rigidity. Its construction with ceramic balls and a phenolic cage contributes to reduced friction, lower operating temperatures, and extended service life, making it ideal for high-reliability and high-precision machinery.
7006 CEGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CEGA | Indicates a universally matchable bearing set. Two bearings are supplied as a matched set (SU) for precise preload and optimal performance when mounted together. |
| HCP4A | Denotes the tolerance class P4A, representing very high precision levels for both dimensional and running accuracy. The "A" signifies an extra light preload. |
7006 CEGA/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of ceramic balls (lower density than steel) and a lightweight phenolic cage significantly reduces centrifugal forces, enabling a high limiting speed of 100,500 rpm.
- Superior Rigidity and Precision: Manufactured to P4A tolerance class with an extra light preload, this bearing provides exceptional running accuracy and stiffness, minimizing deflection under load.
- Enhanced Durability: Ceramic ball material offers excellent wear resistance, electrical insulation, and the ability to operate effectively in a specified temperature range from -30°C to 110°C.
- Optimized Load Capacity: The 15° contact angle is engineered to handle significant combined loads, with a dynamic load rating of 2106 lbf and a static load rating of 1170 lbf.
7006 CEGA/HCP4A Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Speed Machining Centers
- Precision Grinding Spindles
- Medical and Dental Equipment
- Aerospace Instrumentation
