Ceramic bearings, as an important mechanical foundation component, are leading the way in the world of new materials due to their excellent performance that metal bearings cannot match, such as high temperature resistance and super strength. In the past decade, it has been increasingly widely applied in various fields of national economy and people's livelihood.

Main characteristics of ceramic bearings

Ceramic ball bearings are developed for the adjustment, heavy load, low temperature, and lubrication free working conditions in harsh environments in the national defense industry. They are a perfect combination of new materials, new processes, and new structures. Transforming it into civilian technology, ceramic ball bearings can fully cover all application fields of precision, medium speed and above all steel bearings. The inner diameter, outer diameter, and other dimensions of ceramic bearings are standard sizes for P4, P5, and P6 grades of steel bearings established by the state. Due to the low coefficient of thermal expansion, low heat transfer performance, and small elasticity measurement of ceramic materials, installation coordination needs to be taken into account.

In harsh working environments such as high speed, high temperature, low temperature, large temperature difference, vacuum, insulation requirements, and non-magnetic properties, high-performance ceramic bearings are an ideal replacement for the currently used all steel bearings. They have excellent performance indicators such as wide speed range, low heat generation at high speeds, stable performance, long service life, corrosion resistance, no fear of pollution, wear resistance, instantaneous oil deficiency lubrication ability, and high reliability. Ceramic bearings can be widely used in mechanical, chemical, television, vacuum, low-temperature engineering, aerospace, aviation and other fields, with broad development prospects. This project is developed for high-speed, heavy-duty, low-temperature, and non lubricated working conditions used in harsh environments in the national defense industry. It has a high technical content and is a perfect combination of new materials, new processes, and new structures. Its working temperature is within -200 ℃ to+800 ℃, the load is up to 3000Mpa, and the dn value is close to 1.8 million mm. Within r/min, it can be converted into civilian technology and widely used in industries such as high-speed machine tools, low-temperature engineering, high-temperature engineering, and chemical engineering. After appropriate development, the application field can fully cover all application fields of precision, medium speed, and above all steel bearings. The performance price ratio is much better than all steel bearings, and the service life can be increased by more than three times compared to the bearings currently used, saving a lot of money. Shutdown maintenance time, reduced scrap rate, decreased inventory of bearing spare parts, etc; In addition, due to its high technological content, it is impossible to counterfeit and the investment recovery risk is low.
