Shaft Coupling

China's annual requirements of various types, size, coupling the large number of specifications, together with spare parts and the volume of exports has increased year by year, the demand will be greater, so the coupling has a very broad market. Although the coupling of a large market, but also a number of specialized manufacturers, the annual sales of nearly more than one billion yuan, but it can only meet the general needs. The high content of technology, manufacturing is very difficult, life-long large-scale coupling or fail, only a very small number of national manufacturers can produce. China's sales of the lack of standardization of coupling, since only a small number of users attention to the price of neglecting the quality of the phenomenon of the formation of each other to keep the prices down, the price and some even less than cost price, can not guarantee the quality and disturb the market order. There is also a small number of professional manufacturer and has not formed a certain scale, backward technology, obsolete equipment, it is difficult to produce high-quality products, and therefore lost some of the market.
