The material of the flange coupling can be gray cast iron or carbon steel, and cast steel or forged steel should be used under heavy load or when the peripheral speed is greater than 30 m/s.Flange couplings have high requirements for the neutrality of the two shafts. When the two shafts have relative displacement, they will cause additional loads in the machine parts and worsen the working conditions. This is its main disadvantage.However, due to the simple structure, low cost, and large torque transmission, when the speed is low, there is no impact, and the rigidity of the shaft is large.

JSB type serpentine spring coupling is a kind of metal elastic coupling with advanced structure.

The serpentine spring coupling is a metal elastic coupling with advanced structure. It relies on a serpentine spring sheet to transmit torque. The serpentine spring coupling is the most advanced shaft connection transmission component in the international machinery industry today. A very versatile serpentine spring coupling for shaft coupling and transmission components.
