Rolling-element bearings in China: From ancient times to the 20th century

The development of rolling-element bearings in China has spanned a long period. Based on several typical and important cases, the present article reconstructs the history of rolling-element bearings in China by dividing it into four stages according to the various characteristics of the bearings. The first stage represents the origin of rolling bearings in China, which remains controversial because of several suspected races and cages that were likely the components of bearings more than a millennium ago. At the second stage, a type of simple roller bearing was used for astronomical instruments not later than the 13th century based on clear philological and physical evidence. A similar bearing was also applied to an abridged armillary in the 17th century. Another type of spherical thrust bearings with rolling elements, which is a key component of a traditional Chinese windmill, could support a rotating shaft that moves rotationally and at an angle. At the third stage, the Chinese began studying and using the so-called European-style bearing since the 17th century. Moreover, over the last 100 years, the modern rolling bearing industry was gradually established in China, particularly because of the technology transfer from the Soviet Union in the 1950s. At the fourth stage, the Chinese government initiated the relatively rapid development of bearing technology. The government launched the “bearing movement” from the 1950s to the 1960s to establish the modern bearing industry and to promote rolling bearings as replacement for traditional sliding bearings. Furthermore, a number of large professional factories and institutions in China have continually introduced advanced technology and equipment. At present, these companies and institutions play a significant role in the international bearing industry.

Strategic Study of CAE 1999, Volume 1, Issue 3, Pages 79-85
The present review is related to the progress of synthetic rubber industry in this century with special emphasis on the synthetic chemistry, which is the theoretic ground of synthetic rubber. It is forecasted that the living/controlled polymerization of all kinds, their transformation and matallocene system will still take the leading trend in the near future. The progress of the corresponding technology for the manufacture of synthetic rubber will be the gas polymerization process and the polymerization reactor will remain a hot topic to be investigated .
