By Bearing Manufacturer>Bearing News>Looking forward to the prospects of the development of the Chinese Ceramic bearings ?2004-2012 Ceramic bearings as an important basic pieces of machinery, metal bearings that are unmatched excellent performance over the past years, China's ceramic bearings in various fields has been an increasingly wide range of applications. In aerospace, nuclear industry, oil industry, chemical industry, textile industry, food industry, high-speed machine tools (High Speed Bearings) and other high-temperature, high-speed, corrosion-resistant, vacuum, electrical insulation, non-magnetic, the special circumstances of the dry friction ceramic bearings indispensable substitution effect being gradually recognized. Development status of Chinese ceramic bearings Ceramic bearings in domestic research started late.The domestic scale industrialization can form almost no production of ceramic bearings business. Its roots, of course, many, such as the level of technology, talent, capital and other factors that affect, but feel through our years of research and accumulated experience of the current domestic research and development work on Chinese ceramic bearings actually walked into a misunderstanding, on balance exists in several aspects of the problem, a serious system ceramic bearing industry in China. First problems in the research and development of Chinese Ceramic bearings, we currently seen reported are high-speed, high-precision ceramic ball bearings R & D, and is usually around silicon nitride ball dominated mainly to solve the problem of a ceramicball billet system, and the other is a high-precision ceramic processing methods, mostly in the use of high-speed machine tools, CNC machine tools, and high-speed electric spindle occasions, ceramic ball bearings for long life, low noise requirements, from start to finish could notoff-SI3N4 ball billet manufacturing and processing, and study of new materials such as SiC, ZrO2, ZTA, Sailon material. 3.Although the price is relatively high, but under the conditions of the same conditions, the overall economic efficiency of very significant. Contrast, in the practical application of ceramic bearing life is 5 to 10 times the heat-resistant steel bearings, stainless steel bearings 5-15 times; same specifications of the product, the price is significantly lower than abroad. It is reported that the outer diameter of, for example, ceramic ball bearings price $ 80 the Chinese ceramic bearings price is only 110 yuan (about 12 U.S. dollars). Products of the same quality with strong competitiveness in international markets. With China's accession to WTO, foreign large enterprises bearing the continuous influx of new materials, new technology products in quality and price competition will bring greater impact on China's bearing industry, therefore, the use of new materials, new technological innovation traditional bearings industry, domestic bearing technology content and added value, and improve product quality and production of ceramic bearings, Chinese ceramic bearings is to improve market competitiveness and viability, has become an important issue in front of us.
