7008 CE/P4BVG275 Bearing Product Overview & Core Advantages
The 7008 CE/P4BVG275 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, this bearing excels in high-speed scenarios, with a limiting speed of 30,000 rpm. Its 15° contact angle is optimized to support significant combined loads—simultaneously handling radial and axial forces. The phenolic cage and preload availability contribute to its high rigidity and stable performance in precision machinery.
7008 CE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7008 | Basic bearing series, indicating a 40 mm bore, 68 mm OD, and 15 mm width. |
| CE | Specific internal design, typically indicating optimized internal geometry and contact conditions for high performance. |
| P4 | Tolerance class equivalent to ABEC-7, denoting very high precision for dimensions and running accuracy. |
| BVG275 | Indicates a specific preload level and likely a high-performance grease filling for high-speed operation. |
7008 CE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row, angular contact design, combined with the availability of preload, ensures minimal deflection under load, providing exceptional stiffness for precise positioning applications.
- Superior Load Capacity: With a 15° contact angle, this bearing effectively supports combined radial and axial loads. Its dynamic load rating of 2790 lbf ensures reliable performance under demanding conditions.
- Optimized High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the high-performance grease (implied by BVG275) enables stable operation up to the limiting speed of 30,000 rpm.
- Material & Lubrication: Constructed from chrome steel for rings and balls, offering high wear resistance. The bearing is pre-lubricated for immediate use and reliable operation within a temperature range of -30°C to 110°C.
