After researching five or six provinces including the three eastern provinces, Zhejiang, and Shandong, Wang Dongsheng, Executive Deputy Director of the Shandong Technology Transformation Center of the Chinese Academy of Sciences, found the answer: the biggest problem lies in the material, "Without good steel, we can never make high-end bearings. As an indispensable core component in mechanical equipment, bearings support the mechanical rotating body, reduce its friction coefficient, and ensure its rotational accuracy. In his view, whether it's airplanes, cars, high-speed trains, high-precision machine tools, instruments and meters, "every rotating part needs bearings

Recently, Linxi Mingxin Heavy Industry Machinery Co., Ltd. successfully developed P2 level lead screw bearings, with product accuracy four times that of similar products in Japan and Germany; The high load capacity angular contact ball bearings produced by Hebei Youtejie Bearing Co., Ltd. have achieved a precision of P5 level and a rotational speed twice that of similar domestic products... The introduction of multiple products has filled multiple gaps in the Linxi bearing industry and injected new vitality into the high-quality development of the bearing industry
On May 24-26, 2018, in order to promote the implementation of the major short board equipment special project, the Equipment Industry Department of the Ministry of Industry and Information Technology conducted on-site research in Changsha, Zhuzhou, Xiangtan, and other places in Hunan, to understand the development status and existing problems of major short board equipment and bearings in central enterprises such as China Electronics Technology, CRRC, China Aviation Development Corporation, and China Minmetals in Hunan, as well as companies such as Huashu High Tech, Chongde Industry, and Xiangtan Electric, and to listen to suggestions for next policy measures.
There has always been a significant gap between independent component companies and multinational corporations in terms of forward-looking technology reserves. However, it is equally undeniable that in recent years, there have been many independent component companies continuously breaking through in the corresponding technological fields, gradually replacing imported components from easy to difficult, and many companies have also entered the forefront of the industry from "nobody".
