S71914 CE/P4A Bearing Product Overview & Core Advantages
The S71914 CE/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. Engineered to a P4 (ABEC-7) tolerance class, it excels in handling combined loads—simultaneously supporting significant radial loads and axial loads in one direction. Its compact cross-section, with a 70 mm bore and 16 mm width, makes it ideal for space-constrained, high-precision assemblies. The bearing is preloaded and comes pre-lubricated and sealed, ensuring high reliability and long-term performance in demanding operational environments.
S71914 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| C | Designates a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| E | Indicates an optimized internal design with a larger ball complement and reinforced structure for increased load rating. |
| P4A | Specifies the tolerance class P4 (ABEC-7) and likely includes specific running accuracy or preload specifications. |
S71914 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single-row design with a 15° contact angle and preload provides high system rigidity, effectively resisting operational deflection under combined radial and axial loads.
- High-Speed Capability: The lightweight phenolic resin cage minimizes centrifugal forces, while the optimized internal geometry and high-grade lubricant contribute to a high limiting speed of 18,500 rpm.
- Precision Performance: Manufactured to P4 precision class with tight dimensional tolerances, ensuring minimal runout and smooth, quiet operation essential for high-precision machinery.
- Sealed and Lubricated for Life: The integral seals protect against contamination, and the factory-applied lubricant ensures consistent performance across the specified temperature range (-30°C to 110°C), offering a maintenance-free solution.
