We provide comprehensive advisory services in bearing industry for the state's important decision-making departments. We also offer comprehensive technical solutions with respect to bearing selection, design, material, inspection, test, process equipment, training, etc. for bearing and related industries. We have many leading technical experts at home and abroad in the bearing industry, whose research subjects represent technical development trend of China's bearing industry and reach the leading world level in many disciplines. We offer bearing related enterprises and users with complete technical solutions including bearing design, material, inspection, test, technical equipment, etc. (national research center) (The frist industry parks) (The second industry parks) (Deep groove ball bearing industry parks ) |
| 3.Our Product A Leading Enterprise for R&D of Precision Bearings in China We research, develop, and produce more than 20 series and over 500 models of precision bearings. Our main products include precision angular contact ball bearings for spindle of machine tools, angular contact thrust ball bearings for ball screw support, double-direction angular contact thrust ball bearings, NN series of cylindrical roller bearings, YRT bearings of turntable, crossed roller bearings, bearings for high-speed wire precision rolling machine, bearing units for self-detection integrated turntable, etc. And, we provide complete technical solution of precision bearings. China's Base for R&D of Grinding Electric Spindle In 1958, we successfully developed the first electric spindle of China. We are the main drafter of national standards of electric spindle, a vice-director member of Technical Committee of Spindle Functional Components under China Machine Tool and Tool Builders' Association, a core organization for high-speed and high-efficiency machining and process innovation platform of a major state science and technology program "High-grade Numerically Controlled Machine and Basic Manufacturing Equipment". We mainly produce 9 categories including more than 20 series and 400 varieties of electric spindles. We are the China's largest leading enterprise for main spindle units of numerically controlled machine tools. Base for R&D of Bearing Test Technologies and Test Machines in China Since 1960s, we have been engaged in development of bearing testing machine and research of bearing test technologies to provide the most professional solutions of bearing test technologies. Our Astronautics Bearing Laboratory is an important aerospace bearing test base in China. We have developed several hundreds civil bearing test machines and exported them to the United States, Europe and other countries and regions. It is a comprehensive bearing test machines R&D and production base involved in many fields such as aviation, aerospace, high speed rail, wind power, automobile, machine tools, etc.; featuring wide coverage of test bearing dimensions; various test types, complete measuring and controlling items; high degree of automation, reaching the leading national level. Development Base of China Bearing Metals It mainly engages in development of new steel grade for bearings, metallurgical quality inspection and evaluation, experiment and evaluation of contact fatigue life, research on heat treatment technology, heat treatment equipment selection and commissioning, hot work technology improvement and personnel training, analysis on scraps of bearing parts, bearing failure analysis and heat treatment quality inspection.
