High performance ceramic bearing
High performance ceramic bearing is an ideal bearing to replace all steel bearing in harsh working conditions such as high speed, high temperature, low temperature, large temperature difference, vacuum, insulation requirement and non magnetic conductivity. It has the advantages of wide speed range, small heat generation, stable performance, long life, corrosion resistance, pollution resistance, wear resistance, instantaneous oil shortage resistance, strong lubrication ability and high reliability Ceramic bearing can be widely used in machinery, chemical industry, motor, vacuum, low temperature engineering, aerospace, aviation and other fields.
The project is developed for the adjustment, heavy load, low temperature and no lubrication conditions in the harsh environment of the national defense industry. It is a perfect combination of new materials, new processes and new structures. Its engineering temperature is within ― 200 to 200, the load is up to 3000mpa, and the DN value is close to 1.8 million mm. It can be widely used in civil high-speed machine tools, low-temperature engineering, high-speed motor, chemical industry and other industries. After proper development, the application fields can completely cover all the application fields of precision and medium speed all steel bearings. The performance price ratio is far better than that of all steel bearings, and the service life can be increased by more than 3 times than that of the bearings used now, In addition, due to the high technology content, it is impossible to counterfeit and the investment risk is small.
Ultra precision ceramic ball can be widely used in high-performance bearings and ball valves; ceramic bearings can be used in high-speed machinery, light industry, instrumentation, automobile, aerospace and other fields. This kind of bearing is a typical two high-tech products, that is, high-tech content and high added value. It is internationally recognized as the mainstream product of the future bearing, which will occupy 40 ~ 60% of the bearing market share. The recent market is about 1 billion, mainly used in high-speed machine tools, high-speed motors and low-temperature equipment. At present, the development and production can gradually replace all application fields of precision and medium speed bearings. The price of precision ceramic bearings is 1.5-1.8 times higher than that of steel bearings of the same type, and the service life can be extended at least three times.
In addition, the automotive industry is one of the potential application fields of ceramic bearings, and its consumption is huge; the ceramic bearing technology for high reliability fields such as military industry and aviation is currently under development with high price, but the technology is difficult and the consumption is medium.
