7006 CD/HCP4AH Bearing Product Overview & Core Advantages
The 7006 CD/HCP4AH is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and rigidity. This single-row bearing features a 15° contact angle and is supplied as a universally matched pair (set of 2), enabling it to accommodate combined radial and axial loads simultaneously. Its P4A super-precision tolerance and ceramic ball construction deliver superior high-speed performance and extended service life, making it an ideal solution for high-reliability machinery.
7006 CD/HCP4AH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Standard bore diameter (30 mm) and dimension series |
| CD | Universal matching designation; two bearings are supplied as a pre-configured set with optimized internal clearance and preload |
| HC | Hybrid Ceramic construction, featuring ceramic balls for reduced friction and higher speed capability |
| P4A | Super-precision tolerance class, providing extremely tight dimensional and running accuracy |
7006 CD/HCP4AH Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Design: The use of ceramic balls significantly reduces centrifugal forces and operating temperature, enabling a limiting speed of 56,000 rpm. This construction also provides electrical insulation and enhanced durability.
- High Rigidity & Load Capacity: The 15° contact angle and universal matching (CD) arrangement allow the bearing pair to handle significant combined loads while maintaining system stiffness.
- Precision Engineering: Manufactured to P4A tolerance class with a phenolic resin cage, this bearing ensures minimal vibration and optimal performance in high-speed applications.
- Optimized for Preload: The bearings are supplied as a matched set, pre-configured for simplified installation and immediate achievement of the required preload and running accuracy.
7006 CD/HCP4AH Bearing Typical Application Areas
This precision bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (high-speed milling and grinding)
- Precision Robotics and Automation Systems
- High-Frequency Motor Spindles
- Medical and Dental Equipment (e.g., high-speed handpieces)
