7000 CE/P4AH Bearing Product Overview & Core Advantages
The 7000 CE/P4AH is a single-row angular contact ball bearing engineered for high-precision applications requiring superior rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing is designed to accommodate primarily axial loads in one direction and combined loads. Its compact design, featuring a 10 mm bore and 8 mm width, makes it ideal for space-constrained, high-speed machinery. The phenolic cage and optimized 15° contact angle contribute to exceptional high-speed performance and smooth operation.
7000 CE/P4AH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a specific internal design with a 15° contact angle and optimized internal geometry for high-speed operation. |
| P4A | Denotes a high-precision tolerance class with very tight dimensional and running accuracy tolerances, suitable for machine tool spindles and other precision equipment. |
| H | Signifies that the bearing is supplied with a preload, enhancing system rigidity and reducing vibration for improved positional accuracy. |
7000 CE/P4AH Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row angular contact design, combined with the P4A tolerance class and factory-applied preload, provides exceptional system stiffness and rotational accuracy, minimizing deflection under load.
- Optimized Load Capacity: Engineered to handle high axial loads in one direction and combined (axial and radial) loads efficiently, thanks to the 15° contact angle.
- Superior High-Speed Performance: The lightweight phenolic resin cage ensures stability and low friction at high rotational speeds, supporting a limiting speed of 140,000 rpm. The open seal type minimizes heat generation.
- Durability & Reliability: Constructed from chrome steel for both rings and balls, ensuring high fatigue life and resistance to wear in demanding operating environments.
7000 CE/P4AH Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for applications requiring high speed, accuracy, and rigidity, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Gearboxes
