RINGFEDER TNM G Elastic Couplings

TNM G series kits are complete sets of parts for assembling the RINGFEDER TNM G 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.

One of the hubs is composed of two parts – a flange hub and an outer claw ring, which is bolted to the hub. Therefore, when replacing the worn flexible element, it is not 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.
