Overview of research and development of domestic and foreign ceramic bearings and ceramic ball bearings

Ceramic bearings and ceramic ball bearings are a wonderful combination of new types of bearings, which are a good combination of new processes, new materials and new structures. As a basic part of the rotation of the carrier machinery, it has excellent performance unmatched by metal bearings. It is widely used in various special environments and harsh environments. Because of its high temperature resistance, low cold resistance, corrosion resistance, electrical insulation, magnetic resistance, low density and high strength, it is the leader in the new material world.

In the past ten years, it has been widely used in various fields of national economy and people's livelihood. In the fields of aerospace, navigation, nuclear industry, petroleum, chemical, textile industry, machinery, metallurgy, electric power, new energy, food, locomotive, subway, high-speed machine tools and scientific and technological defense, we need high temperature, high speed, deep cold, It is flammable, explosive, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction, easy to rust and other special working conditions. The indispensable substitute effect of ceramic bearings is gradually being recognized.

With the continuous advancement of processing technology and the increasing level of technology, the cost of ceramic bearings has been declining. From the past, it has only been applied in a small range of high, precise and sharp fields, and has been gradually extended to various industrial fields of the national economy. Production makes the market price gradually close to practical use, reaching the level acceptable to users.

Through batch and long-term use tests in different industries. Many successful cases have experienced the maintenance-free and long life brought by ceramic bearings and ceramic ball bearings. The advantages of high stability and low cost. Ceramic bearings and ceramic balls have gone from the research and trial production stage to the mass production stage, and the wave of large-area application has already arrived.
