S7012 CE/P4BVG275 Bearing Product Overview & Core Advantages
The S7012 CE/P4BVG275 is a single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. Operating under a P4 (ABEC-7) tolerance class, it is designed to handle significant combined loads, primarily thrust loads in one direction, while also supporting radial loads. Its key advantages include a 15° contact angle for optimal thrust capacity, a phenolic resin cage enabling high-speed operation, and factory-applied lubrication for immediate use. This bearing is preloaded, ensuring high rigidity
S7012 CE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7012 | Basic bearing designation, indicating a high-precision angular contact ball bearing series. |
| CE | Indicates a 15° contact angle and specific internal design optimizations for high-speed performance. |
| P4 | Denotes the tolerance class, equivalent to ABEC-7, signifying very high dimensional and running accuracy. |
| BVG275 | Specifies the preload level and likely the specific high-performance grease lubrication used for the specified temperature range. |
S7012 CE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Axial Stiffness: The single-row design with a 15° contact angle and the application of preload work in concert to provide exceptional axial rigidity, minimizing deflection under thrust loads and ensuring precise shaft positioning.
- Superior Load Capacity: Engineered to support combined loads, this bearing efficiently handles substantial one-direction thrust loads alongside radial loads, with a dynamic load rating of 3870 lbf and a static load rating of 2902 lbf.
- Optimized High-Speed Performance: The lightweight phenolic resin cage (Phenolic) reduces centrifugal forces, while the precision-ground chrome steel components and optimized internal geometry contribute to a high limiting speed of 20,000 rpm.
- Sealed and Lubricated for Longevity: As a sealed and lubricated unit, it is protected from contamination and comes pre-lubricated with a grease suitable for a wide temperature range of -30°C to 110°C, offering long-term, maintenance-free operation.
