S7020 CE/P4BVG275 Bearing Product Overview & Core Advantages
The S7020 CE/P4BVG275 is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. This single-row bearing features a 15° contact angle and is supplied with a preload, making it ideal for setups requiring high rigidity and minimal axial play. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, while the sealed design with factory-applied lubrication provides long-term, maintenance-free operation. This bearing is engineered to handle combined loads, offering excellent performance in high-speed and high-precision environments.
S7020 CE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Specific internal design and preload class | Optimized for high rigidity and precise rotational accuracy. |
| P4 | Tolerance class equivalent to ABEC-7 | Ensures extremely tight dimensional and running tolerances for superior performance. |
| BVG275 | Sealing and lubrication specification | Provides effective protection against contaminants and comes pre-lubricated for long service life. |
S7020 CE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 15° contact angle and application of preload significantly increase system stiffness, reducing deflection under load and ensuring precise shaft positioning. The P4 tolerance class guarantees minimal runout and vibration.
- Optimized Load Capacity: Engineered to support combined radial and axial loads simultaneously. The high-grade chrome steel rings and balls provide a high dynamic load rating of 10102 lbf.
- Superior High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 12,300 rpm. This makes the bearing suitable for demanding high-speed applications.
- Maintenance-Free Operation: The sealed design with factory-applied lubrication effectively excludes contaminants and retains grease, enabling reliable performance across a wide temperature range (-30° to 110 °C) without the need for re-lubrication.
S7020 CE/P4BVG275 Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance machinery and systems, including:
- Machine Tool Spindles
- High-Speed Precision Spindles (e.g., for grinding, milling)
- Industrial Pumps and Compressors
- Precision Medical and Laboratory Equipment
- Robotic Arms and Precision Gearboxes
