Ceramic Bearings: Internationally recognized future mainstream products

High-performance ceramic bearings are ideal bearings for replacing all-steel bearings currently used in high-speed, high-temperature, low-temperature, large temperature difference, vacuum, insulation requirements, non-magnetic and other harsh working environments. They have a wide range of speeds and high-speed operation. It has excellent performance indicators such as stable performance, long life, corrosion resistance, no fear of pollution, anti-wear, strong resistance to transient oil shortage and high reliability.
Ceramic bearings are developed for the adjustment, heavy load, low temperature and non-lubrication conditions of the harsh environment in the defense industry. The technical content is very high, which is the perfect combination of new materials, new processes and new structures. It can be converted into civilian technology, which can be widely used in civil high-speed machine tools, low-temperature engineering, high-speed motors, chemical industry, etc. After proper development, the field of use can completely cover all the application fields of precision, medium-speed and above all-steel bearings. The price ratio is far superior to that of all-steel bearings, and the service life can be more than 3 times longer than the current bearing life, saving a lot of downtime and maintenance time, reducing waste, reducing bearing spare parts, etc. In addition, due to high technical content, it is impossible to counterfeit, investing low risk.
Ultra-precision ceramic balls can be widely used in high-performance bearings and high-performance ball valves; ceramic bearings can be used in high-speed machinery, light industry, instrumentation, automotive, and aerospace.
According to industry experts, this type of bearing is a typical two-high product, namely high-tech content and high added value. It is an internationally recognized mainstream product of future bearings and will occupy 40 to 60% of the bearing market. The recent market is 1 billion. The yuan is mainly used in high-speed machine tools, high-speed motors, and low-temperature equipment. At present, it can gradually replace all application fields of precision and medium-speed bearings. The price of precision ceramic bearings is 1.5 to 1.8 times that of the same type of steel bearings. And life expectancy can be extended by at least 3 times.
In addition, the automotive industry is one of the potential applications of ceramic bearings, and the amount of use is extremely high; ceramic bearing technology for high reliability fields such as military and aviation is currently under development, and the price is high, but the technical difficulty is large and the dosage is medium.
In summary, high-performance ceramic bearing technology has enormous economic benefits and extensive social benefits.
