RINGFEDER TNM E Elastic Couplings
TNM E series kits are complete sets of parts for assembling the RINGFEDER TNM E shaft coupling.
RINGFEDER TNM E are torsionally flexible, puncture-proof shaft couplings. 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.
Each of the hubs consists of only one part. Therefore, when replacing a worn flexible element or disassembling and assembling, it is necessary to move the individual machine parts. TNM coupling hubs are made of grey cast iron as unbored. They are therefore supplied as semi-finished products and the bore must be adjusted before mounting the coupling on the shafts.
TNM couplings can be used for both directions of rotation and each mounting position.
Formerly they were sold under the TSCHAN NORMEX designation.
