Our torsionally rigid, flexible 'RING-flex®' disc couplings can compensate for angular, axial, and radial misalignments while transmitting torque backlash-free between driver and driven components. They operate without wear or maintenance, never need lubrication, and, due to their all-metal construction, are insensitive even to very high temperatures. RING-flex® couplings are pre-engineered to be connected to the shaft with variable RINGFEDER® keyless locking devices.
