RINGFEDER TNS Hubs
TNS hubs are parts designed for RINGFEDER TNS shaft 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. TNS coupling hubs are made of steel as unbored. They are therefore supplied as semi-finished products and the bore must be adjusted before mounting the coupling on the shafts.
Formerly they were sold under the TSCHAN-S designation.
