7006 ACE/HCP4A Bearing Product Overview & Core Advantages
The 7006 ACE/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This single-row bearing features a 25° contact angle and is supplied with a preload, delivering superior running accuracy and high rigidity. Its optimized design, utilizing ceramic balls and a phenolic cage, enables outstanding high-speed performance and thermal stability. It is ideally suited for machine tool spindles and other high-precision machinery where reliability under combined loads is critical.
7006 ACE/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). |
| ACE | Signifies a 25° contact angle and the application of a specific preload for enhanced rigidity. |
| HCP4A | Indicates the P4 (ABEC-7) tolerance class for ultra-precise dimensional and running accuracy. The 'A' denotes a specific internal design and pairing arrangement. |
7006 ACE/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Running Accuracy: The application of a preload eliminates internal clearance, resulting in significantly increased stiffness and minimal runout, which is essential for high-precision machining.
- Superior High-Speed Capability: The combination of lightweight ceramic balls (silicon nitride) and a phenolic resin cage reduces centrifugal forces and friction, enabling a high limiting speed of 65,000 rpm.
- Excellent Load Capacity: The 25° contact angle is optimized to efficiently handle substantial combined loads (radial and axial loads acting simultaneously).
- Thermal and Dimensional Stability: The phenolic cage and ceramic balls offer low thermal expansion and stable performance across the operating temperature range of -30°C to 110°C.
7006 ACE/HCP4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Rotary Tables
- High-Frequency Motors
- Aerospace Gyroscopes and Instrumentation
- Medical and Dental Handpieces
