Ball bearing foreign markets at home and abroad market: ball bearing application domain expands gradually, in the international market demand is gradually increasing, has huge development potential.
At present, the United States, Japan, ceramic porcelain ball bearing technology in the world leading level.
Because of the silicon nitride material itself advantages, silicon nitride ball bearing can be in high temperature, high speed, high pressure, cryogenic, vacuum, strong corrosion, the magnetic resistance, no lubrication, easy to wear and so on under the special environment work, and steel bearing can't meet the requirements.
Silicon nitride balls are now widely used in aircraft engine, all kinds of high precision, high speed machine tools, cars, car, subway, electric machinery, petrochemical machinery, metallurgical machinery and other fields.
Bearing research in China started later than developed industrial countries for nearly 30 years, but the research and application of ball bearing, test fast pace of progress.
To develop the national machine tool industry, improve the accuracy of machine tool products, meet other special application field, bearing will play a decisive key role, and adoption of new type nanocomposites is a trend to improve precision and performance of bearing products.
