Our History

Since 1958, ZYS has been committed to the research and development of “high-tech, precise, cutting-edge, specialized and special” bearings, and relevant products.Our predecessor, Luoyang Bearing Research Institute, was the only first-class comprehensive research institute in China bearing industry. That is why ZYS accumulates and develops a large number of advanced competitive core technology. Possessing the first-class bearing design technology (design theory, design software, etc. ) and bearing testing technique (testing methods, testing means, etc. ), ZYS has set up a doctoral scientific research workstation, and a strong team full of domestic and foreign experts, whose main researches represent the technology developing direction of China bearing industry. As a leading role in multiple key disciplines, ZYS always provides comprehensive technology advisory services about bearing industry for national important decision-making departments.
