S7019 CE/P4A Bearing Product Overview & Core Advantages
The S7019 CE/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 15° contact angle, it is optimized to handle high combined loads, primarily thrust loads in one direction along with significant radial loads. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for high-speed spindles and other high-precision machinery. The bearing comes pre-lubricated and sealed for immediate, maintenance-free operation.
S7019 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7019 | Basic bearing series, indicating a metric, single-row angular contact ball bearing with a 95mm bore, 145mm OD, and 24mm width. |
| CE | Indicates a preload class applied to the bearing, enhancing rigidity and minimizing axial/radial play for superior performance in precision applications. |
| P4A | Specifies the tolerance class P4 (ABEC-7), denoting very high precision. The "A" may indicate a specific contact angle (15° in this case) or internal design optimization. |
S7019 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 15° contact angle and applied preload (CE) provides exceptional system stiffness, critical for minimizing deflection under load in high-speed applications.
- Superior Load Capacity: Engineered to support high combined radial and axial loads, with a dynamic load rating of 9945 lbf and a static load rating of 8550 lbf.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 12,700 rpm. The P4 precision grade ensures smooth, low-vibration operation at these speeds.
- Sealed and Lubricated for Life: As a sealed and pre-lubricated bearing, it is protected from contamination and is ready for immediate installation, offering long-term, maintenance-free service within its specified temperature range.
