Product Overview and Core Advantages
The S71924 CE/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (radial and axial loads in one direction), this bearing features P4 (ABEC-7) precision tolerance and is preloaded for optimal stiffness and minimal runout. Its compact design, combined with sealed construction and factory-applied lubrication, ensures reliable performance in demanding environments where precision and long service life are critical.
S71924 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | High-precision, preloaded bearing with optimized internal geometry | Enhanced rigidity and running accuracy |
| P4A | P4 (ABEC-7) tolerance class with specific dimensional and running accuracy requirements | Superior precision for high-speed and high-accuracy applications |
Structural Features and Performance Benefits
- High Rigidity and Precision: The 15° contact angle and preload configuration provide exceptional system stiffness, minimizing deflection under load and maintaining precise shaft positioning.
- Optimized Load Capacity: Designed to handle significant combined radial and axial loads simultaneously, making it ideal for applications with complex loading conditions.
- High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio and reduced friction, contributing to the bearing's limiting speed of 11,200 rpm.
- Sealed and Lubricated Design: Integrated seals protect against contamination while factory-applied lubrication ensures immediate operation and extended service intervals.
- Premium Materials: Manufactured from chrome steel for rings and balls, ensuring high durability and fatigue resistance under demanding operating conditions.
