7009 CDTP/HCP4B Bearing Product Overview & Core Advantages
The 7009 CDTP/HCP4B is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and performance. Engineered as a single bearing with a 15° contact angle, it is optimized to handle combined loads—significant radial loads and axial loads in one direction. Its P4 (ABEC-7) tolerance class ensures ultra-precise rotational accuracy, making it ideal for high-speed spindles and other high-reliability applications. The combination of a ceramic ball material and a phenolic cage contributes to its superior high-speed capabilities and thermal stability.
Model Code Breakdown
| Model Segment | Technical Meaning |
|---|---|
| 7009 | Basic bearing series and size designation (45mm bore, 75mm OD, 16mm width). |
| C | Specifies a 15° contact angle. |
| D | Indicates a high preload is applied. |
| T | Refers to the phenolic (textile) cage construction. |
| P | Indicates the bearing is supplied with pre-lubrication. |
| HCP4B | Denotes the P4 (ABEC-7) tolerance class and specific internal design enhancements for high precision. |
7009 CDTP/HCP4B Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The application of a high preload (D) significantly increases bearing rigidity, minimizing deflection under load and ensuring precise shaft positioning, which is critical for machining accuracy.
- Superior High-Speed Performance: The combination of a lightweight phenolic cage (T) and ceramic balls reduces centrifugal forces, lowers operating temperatures, and allows for a very high limiting speed of 22,000 rpm.
- Excellent Load Capacity: The 15° contact angle (C) design provides robust combined load capacity, effectively handling both radial and one-directional axial forces.
- Precision & Longevity: Manufactured to P4 tolerance with optimized internal geometry, this bearing ensures smooth, quiet operation and extended service life in demanding conditions.
7009 CDTP/HCP4B Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Instrumentation
- High-Frequency Motors
- Medical Equipment (e.g., Dental handpieces)
- Aerospace & Defense Systems
