Grid Couplings – Components
Hubs
The grid coupling hubs are made from high tensile alloy steel and is precision machined to ensure superior performance and long life.
The hub attaches to the shafts of the machinery, providing a secure and stable connection point.

spring Element
The spring element in a grid coupling is a flexible, metallic grid-shaped component made of high-strength alloy steel. It is tempered to spring hardness and precision shot peened to increase its fatigue strength.
This grid-like structure fits between the teeth of the coupling hubs, connecting the two shafts.
