S7001 CEGA/P4A Bearing Product Overview & Core Advantages
The S7001 CEGA/P4A is a high-precision, single-row angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Its primary advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and unidirectional axial loads. Manufactured to the stringent P4A tolerance class and featuring a phenolic cage with a 15° contact angle, this bearing is engineered for high-speed operation and superior performance in compact, high-reliability applications.
S7001 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CEGA | Indicates a specific internal design and cage type. The phenolic (resin) cage is lightweight and ideal for high-speed applications. |
| P4A | Denotes an ABEC 7 / ISO P4 precision class with additional geometric tolerances for superior running accuracy and low noise/vibration. |
S7001 CEGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P4A tolerance class ensures minimal runout and vibration, providing stable and precise shaft guidance. The optimized internal geometry and 15° contact angle deliver high system rigidity.
- Superior Load Capacity: The angular contact design is specifically engineered to support combined radial and axial loads efficiently in one direction.
- High-Speed Performance: The lightweight and robust phenolic cage (CEGA) minimizes centrifugal forces and friction, enabling higher limiting speeds and reduced operating temperatures.
- Sealed & Pre-Lubricated: As a sealed bearing, it is filled with high-quality grease, offering protection against contamination and providing long-term, maintenance-free operation within its specified temperature range.
