7007 CDTP/P4B Bearing Product Overview & Core Advantages
The 7007 CDTP/P4B is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, it is preloaded and lubricated from the factory, ensuring optimal performance and simplified installation. Its primary strength lies in its ability to handle combined loads—simultaneously supporting significant radial and axial forces—making it an ideal choice for high-speed spindles and other precision machinery where high rigidity and positional accuracy are critical.
7007 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Basic bearing series designation, indicating a 35mm bore, 62mm OD, and 14mm width. |
| CD | Specifies a 15° contact angle and a specific internal design optimized for high-speed operation and preload. |
| T | Indicates the cage is made of phenolic resin, which offers low weight and excellent performance at high speeds. |
| P | Denotes the bearing is preloaded, enhancing system rigidity and reducing axial/radial runout. |
| P4B | Specifies the tolerance class P4 (ABEC-7), representing very high precision in dimensions and running accuracy. |
7007 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The angular contact design combined with factory-applied preload provides superior system stiffness, minimizing deflection under load and ensuring precise shaft positioning.
- Superior Load Capacity: Engineered to support combined radial and axial loads simultaneously. With a dynamic load rating of 3510 lbf and a static load rating of 2138 lbf, it is built for demanding applications.
- Optimized High-Speed Performance: The lightweight phenolic cage (T) reduces centrifugal forces, while the 15° contact angle (CD) and factory lubrication contribute to a high limiting speed of 24,000 rpm.
- Precision & Longevity: Manufactured to P4 precision tolerances from high-grade chrome steel, this bearing ensures smooth, quiet operation and extended service life in precision applications.
7007 CDTP/P4B Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles (e.g., CNC milling, grinding, and high-speed machining centers)
- Precision Rotary Systems
- High-Frequency Motors
- Medical and Laboratory Equipment
