Hybrid ceramic bearings vs. full ceramic bearings
Hybrid ceramic bearings refer to bearings whose inner and outer rings and rolling elements are made of steel and ceramic. The inner and outer rings are made of steel, and the rolling elements are made of ceramic materials. Full ceramic bearings refer to bearings whose inner and outer rings and rolling elements are made of ceramic materials. The main advantages are low friction coefficient, high rigidity, good corrosion resistance and other characteristics. The manufacturing process of hybrid ceramic bearings is simpler than that of full ceramic bearings, and the cost is relatively lower. So, what is the difference between hybrid ceramic bearings and full ceramic bearings? Let us analyze and explain it in detail in this article.
Only the inner and outer rings or rolling elements of hybrid ceramic bearings are made of ceramic materials, and the rest are made of metal materials. The inner and outer rings and rolling elements of full ceramic bearings are made of ceramic materials, which have the characteristics of high temperature resistance and corrosion resistance.
Different performance
Compared with full ceramic bearings, hybrid ceramic bearings have higher strength and reliability, but the hardness of ceramic balls is higher than that of steel bearings, which will cause certain wear on other parts during operation. Full ceramic bearings have better wear resistance, corrosion resistance, high temperature performance and corrosion resistance, and can maintain good stability in harsh working environments.
Different applications
The application range of hybrid ceramic bearings is relatively small, and they are usually only suitable for general industrial environments. Full ceramic bearings have good corrosion resistance and high temperature resistance, so they are suitable for use in harsh environments such as high temperature and corrosion. Although hybrid ceramic bearings and full ceramic bearings are both made of ceramic materials, there are differences between the two in terms of materials, applicable environments, functions, etc. According to actual needs, choosing suitable bearings can better play their characteristics and improve the use effect of mechanical equipment.
