S71919 CE/P4A Bearing Product Overview & Core Advantages
The S71919 CE/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered with a 15° contact angle and P4 (ABEC-7) tolerance class, this bearing excels at simultaneously handling combined radial and axial loads. Its compact design, featuring a phenolic cage and factory-applied lubrication, makes it an ideal solution for high-speed spindles and other precision machinery where reliability and long service life are critical.
S71919 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S71919 | Basic bearing designation for a high-precision angular contact ball bearing series. |
| CE | Indicates a 15° contact angle and specific internal design optimized for high-speed operation and rigidity. |
| P4A | Denotes a P4 (ABEC-7) tolerance class, ensuring extremely tight dimensional and running accuracy for precision applications. |
S71919 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 15° contact angle and P4 tolerance class provides stable, high-rigidity support for spindles, minimizing deflection under load and ensuring exceptional running accuracy.
- Optimized Load Capacity: Engineered to efficiently support combined radial and axial loads, with a dynamic load rating of 7020 lbf and a static load rating of 5738 lbf.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the pre-applied high-quality grease enables a high limiting speed of 14,000 rpm.
- Sealed and Lubricated for Life: As a sealed bearing with factory-applied lubrication, it is protected from contamination and is typically maintenance-free within its specified temperature range of -30°C to 110°C.
