    The problems existing in the domestic ceramic bearing in the bearing market

    We are all common bearing is high speed, high precision ceramic ball bearing in terms of research and development, and is generally around silicon nitride balls is given priority to, generally speaking, one is the blocking of the ceramic ball, the other one is the processing technology of the high accuracy ceramic ball, on the use of more belong to high speed machine tools, CNC machine tools, such as high speed motorized spindle, long life and low noise requirements of ceramic ball bearing, from beginning to end have not been able to out of SI3N4 ball billet manufacturing and processing, generally refers to a new type of materials: ZrO2 ZTA as well as steatite SiC, Sialon etc materials is small, can be seen in the practical application, the application of ZrO2 manufacturers accounted for the vast majority. 


    Good material due to concerns about the cost and process cannot be use. Haining kang knight bearing manufacturing co., LTD., the production of low noise, dry friction, anti-static ceramic ball bearings NMB Japanese company and the same specifications of the ceramic ball bearing a detailed comparison and difference on the db 2 db, good product can do 20 db. With foreign similar products. But the price is positioned in NMB about 15% of the company. Can be used to form a complete set with domestic appliances. But this price is higher compared with the ordinary bearing, are generally used in export more high-end equipment or parts can be seen. How to look from the bearing number bearing classification 


    In addition, it is important to note that the production of ceramic bearings and ceramic ball bearing is the industrialization of high-tech ceramics and bearing manufacturing technology, the product of the two requirements is very high, if you don't solve the problem of ceramic and bearing industry union, can guarantee high quality competitive price. Many businesses before manufacturing of ceramic materials with technology is not enough, can produce ceramic materials enterprise manufacturing bearings, professional knowledge can not meet the current needs. At present, some bearing manufacturing enterprise of ceramic bearings and ceramic ball bearing on the professional knowledge, especially the ceramic materials science and engineering research is relatively small, creating a is made of ceramic material is ceramic bearing, bearing in ceramic ball is ceramic ball bearings. 


    Normally only in the domestic ceramic bearing no electricity, no magnetic, corrosion resistance, low speed can run to run the environmental requirements is not high. And domestic ceramics manufacturing has a lot of problems, although the technology is still can't keep up with, blind pursuit of low prices caused by the performance of the material can't reach the expected effect. The use of more units lose faith in ceramic bearings and ceramic ball bearings. Roll crusher bearing selection should pay attention to? 


    Generally speaking, this kind of high technical content, through investment in technology intensive and capital intensive into two stages, the industrialization production of ceramic bearing, both to overcome many technical difficulties, the original capital accumulation and continuous reclosing must serve the ceramic bearings and ceramic ball bearings to the higher quality of field development. And use problems and require large capital investment, but also grasp market positioning, industry insight are needed to develop domestic ceramic bearings and ceramic ball bearing the high level of responsibility. Low price competition will inevitably bring churning out and further deterioration of the market.
