JS Grid Coupling
The JS Grid Coupling is axially embedded in two halves with serpentine spring by more than 36%. Serpentine spring with trapezoidal cross-section is made of high-quality spring steel. It is processed by strict heat treatment and undergoes special processing, and thus has good mechanical properties. As a result, the service life of the coupling is much longer than that of non-metallic elastic element couplings (such as elastic sleeve pin couplings and nylon rod pin couplings).
