The application field of ceramic ball bearings in the international market is gradually expanding, the demand is gradually increasing, and there is huge development potential. At present, the United States and Japan ceramic ball bearing technology ranks in the world's leading level.
Due to the advantages of silicon nitride ceramic materials, silicon nitride ceramic ball bearings can work in special environments such as high temperature, high speed, high pressure, deep cold, vacuum, strong corrosion, anti-magnetic, non-lubricated, and easy to wear, while steel bearings cannot fulfil requirements. Silicon nitride ceramic balls have been widely used in aviation engines, various high-precision, high-speed machine tools, automobiles, racing cars, subways, motors, petrochemical machinery, metallurgical machinery and other fields.
China's ceramic bearing research started nearly 30 years later than industrially developed countries, but China's ceramic ball bearing research, application, and test have made rapid progress. Vigorously develop the national machine tool industry, improve the accuracy of machine tool products, and meet other special applications. Ceramic bearings will play a decisive key role. The use of new nano-composite ceramic materials is a trend to improve the accuracy and performance of ceramic bearing products.
