GRID COUPLINGS can carry considerable torques despite their compact sizes. This type of all-metal flexible coupling is mainly used to reduce the transmission of vibration and shock loading, while allowing both angular and parallel misalignments within their operational limits. When a heavy overload happens, or an excessive misalignment occurs, the grid and its cover fail, acting as a safety device. This way, the transmission of torque is interrupted, and other costlier components of the drive are protected against damage.
