Grid Couplings

Grid Couplings

Grid couplings use two slotted hubs with a steel grid running between them to transmit torque. Grid couplings are available in horizontal and vertical styles. The grid coupling flexes by allowing the grid to slide along the slots in the hubs. Grid couplings can only accommodate 1/3° misalignment and transmit torque from 422 in-lbs to 2,700,000 in-lb (3,656,555 Nm).

Grid couplings are noted for reducing vibration, absorbing shock and compensating for misalignment. The flexible nature of the spring-like grid absorbs impact energy by spreading it out over time, thus reducing the magnitude of the peak loads. This is possible because of the progressive contact that occurs between the curved profile of the hub teeth and the flexible grid. Therefore, as the load increases, more of the tooth comes into contact with the grid, thus supplying superior protection and supreme performance. Grid Couplings are fully interchangeable between manufacturers. The grid coupling is noted for being simple to install and maintain, reducing downtime.
