7006 ACEGA/HCP4A Bearing Product Overview & Core Advantages
The 7006 ACEGA/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This single bearing features an Extra Light (A) preload and a 25° contact angle, optimized for high rigidity and precise operation under combined loads. Manufactured to P4A tolerance class, it delivers superior running accuracy. A key advantage is its Universal Matchable (SU) designation, allowing it to be precision-matched with other bearings in sets (up to 4) for optimal stiffness and load distribution in complex arrangements.
7006 ACEGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 13mm width). |
| AC | Angular Contact geometry, designed to support combined radial and axial loads. |
| EGA | Specifies the preload level (Extra Light / Class A). |
| HC | Indicates the use of Hybrid Ceramic components (Ceramic balls with steel rings). |
| P4A | The tolerance class, denoting very high precision for inner and outer ring runouts and widths. |
7006 ACEGA/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, lowers operating temperatures, and extends service life, especially in high-speed applications (up to 71,500 rpm).
- Phenolic Resin Cage: The lightweight and robust cage material ensures stable operation at high speeds and offers good resistance to centrifugal forces.
- High Precision & Rigidity: The P4A tolerance class and 25° contact angle provide exceptional running accuracy and system stiffness, making it ideal for precise positioning.
- Optimized for Matched Sets: As a Universal Matchable (SU) bearing, it can be supplied in pre-engineered sets of up to 4 bearings, ensuring uniform load sharing and maximum rigidity in duplex, triplex, or quadruplex arrangements.
7006 ACEGA/HCP4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-performance machinery where speed, accuracy, and reliability are critical. Key applications include:
- High-Speed Machine Tool Spindles
- Precision Grinding Spindles
- High-Frequency Motors and Spindles
- Advanced Robotics and Automation
- Medical and Dental Equipment Spindles
- Aerospace Actuation Systems
