Suzhou Suwan Universal Joint Company Limited has been manufacturing and supplying u-joints and driveshafts for over 20 years. Apart from being used in assembling our own driveshafts, u-joints, mostly wing style, have been exported to many countries for Caterpillar, Komatsu and other vehicles' aftermarket services. The driveshafts, both wing style and DIN type, have been used for China's manufacturers' OEM applications such as construction machinery, steel rolling mills and oil drilling equipment ever since they were developed in 1990s. From 2002 to 2005, gear couplings, CV driveshafts and diaphragm couplings were successively developed and have been used for oil drilling equipment and steel rolling mills ever since.
