7008 CE/P4A Bearing Product Overview & Core Advantages
The 7008 CE/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to P4 (ABEC-7) tolerance class, this bearing is optimized to accommodate combined loads, primarily handling axial loads in one direction while supporting significant radial loads. Its 15° contact angle and phenolic resin cage contribute to superior high-speed performance, making it an ideal component for demanding, precision machinery where reliability and accuracy are paramount.
7008 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| CE | Contact angle of 15° | Optimized for high-speed operation with balanced axial and radial load capacity. |
| P4A | P4 (ABEC-7) tolerance class with specific internal geometry | Guarantees extremely tight dimensional and running accuracy for precision applications. |
7008 CE/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4 tolerance class with precise internal geometry, ensuring minimal runout and vibration for superior positioning accuracy.
- Optimized High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio and low friction, enabling stable operation at limiting speeds up to 45,000 rpm.
- Superior Load Capacity: The 15° contact angle and high-quality chrome steel construction provide a dynamic load rating of 2790 lbf and static load rating of 1721 lbf, effectively handling combined loads.
- Pre-Lubricated & Open Design: Comes pre-lubricated for immediate use. The open design allows for custom re-lubrication schemes and is suitable for a temperature range of -30°C to 110°C.
7008 CE/P4A Bearing Typical Application Areas
This high-precision angular contact bearing is ideally suited for:
- Machine Tool Spindles: Providing high rigidity and accuracy for CNC machining centers, grinding spindles, and lathes.
- High-Speed Motors and Spindles: Used in electric motors, frequency converter drives, and other high-RPM applications.
- Precision Instrumentation: Critical for optical scanners, measuring devices, and laboratory equipment requiring minimal rotational error.
- Pumps and Compressors: Supporting shafts in high-performance industrial pumps and compressors.
