Plum coupling is a very common application of the coupling, also called jaw coupling, is composed of two metal claw plate and an elastic body. The two metal jaw discs are generally 45 steel, but aluminum alloy can be used for load sensitive applications.    

The primary characteristics are as follow: coupling without lubrication, convenient maintenance, less workload, continuous long-term operation. High strength polyurethane elastic components are wear-resistant and oil-resistant, with large bearing capacity and long service life. Stable and reliable operation, with good damping, buffering and electrical insulation performance. It has higher axial, radial and angular compensation capability. Simple structure, small radial size, light weight, small moment of inertia, suitable for medium-high speed occasions.
