Ceramic bearings are a new type of bearing material that has the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, oil-free self-lubricating, and high rotational speed. They are widely used in many fields. Most cleaning equipment needs to withstand the erosion of corrosive gases or liquids, and traditional metal bearings are difficult to meet their requirements. However, ceramic bearings have excellent corrosion resistance and can operate stably in harsh environments such as strong acids, alkalis, and saltwater. Therefore, ceramic bearings are widely used in chemical equipment, such as acid washing machines, chemical pumps, and other equipment.
