Double disc coupling is a flexible coupling. Often use for servo motor,stepping motor design.We are double flex disc coupling manufacturer in CHINA.
Double disc coupling is a kind of high performance flexible coupling. This coupling with strong metal components, no need to moisten oil, compact structure. High strength, long service life, no rotation gap, not affected by temperature and oil.
Double Disc Coupling
