JS serpentine spring coupling is a metal elastic coupling with advanced structure. Its transmission element is a serpentine spring and its outer protective cover is an aluminum shell. This coupling has the advantages of both rigid and elastic couplings, has good vibration reduction performance, safe startup, can adapt to loads with a wide range of changes, high transmission efficiency, reliable operation, simple structure, easy disassembly and maintenance, long service life, and can replace gear couplings in many occasions. It is widely used in mining, fans, electricity, chemicals, high-pressure pumps and other industries.
