7019 CE/P4A Bearing Product Overview & Core Advantages
The 7019 CE/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and superior performance under combined loads. Engineered to a P4 (ABEC-7) tolerance class, it offers exceptional running accuracy. Its primary advantage lies in its ability to accommodate significant radial loads and unidirectional axial loads simultaneously, making it ideal for high-speed spindles and precision machinery. The bearing is preloaded and lubricated for immediate use, ensuring optimal performance from installation.
7019 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Contact angle of 15° and internal design optimized for high-speed operation. | Enhances high-speed performance and axial load capacity. |
| P4A | Dimensional and running accuracy to P4 tolerance class (ABEC-7). | Guarantees high precision and smooth operation for demanding applications. |
7019 CE/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4 tolerance class with a 15° contact angle, this bearing provides exceptional running accuracy and system rigidity, minimizing deflection under load.
- Superior Load Capacity: The optimized internal geometry and use of 26 high-quality chrome steel balls enable high dynamic and static load ratings (9945 lbf / 8550 lbf), reliably handling combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 20,000 rpm. The CE design further enhances stability at high rotational speeds.
- Prepared for Service: The bearing comes preloaded and lubricated, simplifying installation and ensuring immediate, reliable performance without the need for initial setup.
