Eaton Airflex ER expanding couplings thrive in applications where a disconnection is required without stopping the prime move, or when the driving or driven equipment must be frequently withdrawn from the drive. With a neoprene facing, flexible ER units are used as shaft couplings or holding brakes where engagement occurs at zero speed differential between the element and drum.
