RINGFEDER TNS Elastic Couplings

RINGFEDER TNS are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a rubber or polyurethane element. They transmit torque through pressure-stressed elastic buffers connected to each other in an intermediate ring, which absorbs shocks and torsional vibrations. This element is oil resistant and electrically conductive. TNS coupling hubs are made of steel as unbored.

Formerly they were sold under the TSCHAN-S designation.
