RINGFEDER Shaft Couplings (formerly TSCHAN)

RINGFEDER (formerly TSCHAN) couplings are shaft couplings of the German manufacturer RINGFEDER designed for the transmission of high torques and speeds. Shaft couplings are available in a variety of series and designs, from the smallest elastic and bellows couplings to the largest gear, disc and special shaft couplings.
