These are couplings for engines that transmit power using highly elastic rubber and are excellent at absorbing vibration and shock. They are very soft in the bending direction, and are able to escape the resonance point caused by torsional vibration at or below engine low idle.Being short in the axial direction, they do not require space and can easily engage or isolate input/output simply by moving in the axial direction, facilitating maintenance.
