Coupling Pad are used to compensate for misalignment between shafts. Misalignment can occur due to various reasons such as thermal expansion, manufacturing tolerances, or dynamic loads. Coupling Pads are placed between the coupling halves or elements that connect the shafts. They help to transmit torque from one shaft to another while reducing the impact of misalignment, which can otherwise lead to premature wear and failure of bearings and other components.
