Research and development of ceramic bearings and ceramic ball bearings at home and abroad

Time:2021-01-28 Click:513Return

Ceramic bearings and ceramic ball bearings are a wonderful work in the bearing category, It is a good combination of new technology, new material and new structure. As the basic part of mechanical rotation, it is widely used in various special and harsh environments because of its excellent performance that metal bearing can't compare with. Because of its high temperature resistance, low cold resistance, corrosion resistance, insulation, magnetic resistance, low density, high strength and other properties, it is the leader in the new material world. In the past decade, it has been widely used in various fields of the national economy and people's livelihood. In the fields of aerospace, navigation, nuclear industry, petroleum, chemical industry, textile industry, machinery, metallurgy, electric power, new energy, food, locomotive, subway, high-speed machine tool, scientific research, national defense and military technology, we need to work under the special working conditions of high temperature, high speed, cryogenic, flammable, explosive, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction, easy to rust and so on The substitution of "or" is being gradually recognized. With the continuous progress of processing technology and the increasing level of technology, the cost of ceramic bearing is declining. It has been applied only in some high, precision and sharp fields in the past, and gradually extended to various industrial fields of the national economy. The mass production makes the market price gradually close to practicality, reaching the degree acceptable to users Many successful cases appreciate the advantages of ceramic bearings and ceramic ball bearings, such as maintenance free, long life, high stability and low cost. Ceramic bearings and ceramic balls have moved from the stage of research and trial production to the stage of mass production, and the wave of large-scale application has come.
