The choice of material for a bearing plays a crucial role in determining its performance and lifespan. Bearings are subjected to various types of stress, including high contact pressure, sliding friction, and mechanical wear. The different components—such as the inner and outer rings, rolling elements, and cage—each have specific functional requirements that influence the type of material used. The inner and outer rings, along with the rolling elements, must withstand repeated contact stress and sliding friction. Therefore, these parts require materials with high fatigue strength, hardness, and wear resistance. In contrast, the cage must maintain dimensional stability, possess good mechanical strength, and be easy to process. Depending on the application, additional properties such as impact resistance, heat resistance, and corrosion resistance may also be required. Common materials for the rings and rolling elements include high-carbon chromium bearing steel, such as SUJ2 (also known as AISI 52100, DIN 100Cr6, or BS 535A99). These steels are widely standardized and offer excellent performance under normal operating conditions. For bearings that need to handle heavy impacts, materials like chrome steel, chrome-molybdenum steel, or nickel-chrome-molybdenum steel are used. These materials are often carburized and quenched to create a hard surface layer with a softer core, which improves impact resistance and extends service life. NSK, for example, uses vacuum degassing to produce high-purity materials with low oxygen content, resulting in better quality and longer rolling fatigue life. In special applications, other materials like high-speed steel (for heat resistance) or stainless steel (for corrosion resistance) may be employed. For cages, stamping cages are typically made from low-carbon steel, while more specialized applications may use brass, stainless steel, or even resin-based materials. Cut cages may use high-strength brass, carbon steel, or advanced resins depending on the required performance characteristics. --- **Related Bearing Knowledge:** - How to Avoid Overheating of Imported Bearing Parts - Basic Knowledge of Rolling Bearing Installation - Ball Bearing Processing and Unit Consumption Specifications - Device for Four-Row Cylindrical Roller Bearings in SKF - NSK Bearing Vibration Diagnosis This article is linked from http:// Please cite China Bearing Network http:// Previous: Analysis: Common Methods for Separating Bearings Next: Common Bearing Wear and Countermeasures --- *Note: This text has been rewritten and expanded to ensure it reads naturally, with added context and clarity while maintaining the original meaning.*
