Semi-ceramic bearing refers to the use of semi-ceramic materials to make inner and outer rings or rolling body bearings, full ceramic bearings refers to the bearing inner and outer rings and rolling body are made of ceramic materials, the main advantages are low friction coefficient, high rigidity, good corrosion resistance and other characteristics. The production process of semi-ceramic bearings is simpler than that of all-ceramic bearings, and the cost is relatively lower. So, what is the difference between semi-ceramic bearings and full ceramic bearings?
1. Different materials
Only the inner and outer rings or rolling parts of the semi-ceramic bearings are made of ceramic materials, and the rest are made of metal materials. The inner and outer rings and rolling parts of all ceramic bearings are made of ceramic materials, which have the characteristics of high temperature resistance and corrosion resistance.
2. Different performance
Semi-ceramic bearings have higher strength and reliability than all-ceramic bearings, but the hardness of ceramic balls is higher than that of steel bearings, which will cause certain wear to other parts during operation. All-ceramic bearings have better wear resistance, corrosion resistance, high temperature performance and corrosion resistance, and can maintain good stability in harsh working environments.
3. Different environments apply
The applicable environmental range of semi-ceramic bearings is relatively narrow, usually only suitable for general industrial environments. The all-ceramic bearing has the characteristics of good corrosion resistance and high temperature resistance, so it is suitable for use in harsh environments such as high temperature and corrosion.
Although both semi-ceramic bearings and full ceramic bearings are made of ceramic materials, there are differences in materials, applicable environment, functions and so on. According to the actual needs, the selection of suitable bearings can better play its characteristics and improve the use of mechanical equipment.
