7006 ACDTP/HCP4B Bearing Product Overview & Core Advantages
The 7006 ACDTP/HCP4B is a high-precision single row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. Its primary advantage lies in its ability to accommodate combined radial and axial loads simultaneously, delivered through a defined 25° contact angle. Manufactured to a P4 (ABEC-7) tolerance class, this bearing ensures ultra-precise rotational accuracy and minimal runout. The combination of a phenolic resin cage and ceramic balls contributes to superior high-speed capability, low friction, and extended service life, making it an ideal choice for high-reliability, high-rigidity spindle systems.
7006 ACDTP/HCP4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7006 | Standard bearing series number, indicating a 30mm bore, 55mm OD, and 13mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| DT | Matched set designation (not applicable here, as per spec: Matched arrangement: Single). |
| P | Indicates a preload is applied for enhanced rigidity and precise shaft positioning. |
| HC | Hybrid Ceramic, signifying the use of ceramic balls with steel rings. |
| P4 | The tolerance class (equivalent to ABEC-7), denoting very high precision. |
7006 ACDTP/HCP4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single row design, combined with a defined contact angle and application of preload, provides high system rigidity and minimizes axial and radial deflection under load, which is critical for precision machining.
- Superior High-Speed Performance: The lightweight phenolic cage and low-density ceramic balls reduce centrifugal forces, enabling a high limiting speed of 34,000 rpm. This hybrid construction also reduces heat generation.
- Enhanced Load Capacity: The 25° contact angle is optimized to handle significant axial loads in one direction in addition to radial loads, with a dynamic load rating of 3105 lbf.
- Reduced Friction and Wear: Ceramic balls are harder and smoother than steel, leading to lower friction, reduced operating temperature, and increased resistance to wear, thereby extending bearing service life.
- Temperature Stability: The hybrid design and phenolic cage offer stable performance across a wide temperature range from -30°C to 110°C.
7006 ACDTP/HCP4B Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications where speed, precision, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed CNC machining centers, grinding spindles.
- Precision Instrumentation: High-speed measuring and testing equipment.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Aerospace & Defense: Gyroscopes, radar systems, and other critical rotating assemblies.
- High-Frequency Motors and Spindles: Where low vibration and high rotational accuracy are required.
