Shaft couplings are used to connect two shafts, for transmission torque, compensation of misalignment, damping of vibrations, etc.
Couplings are divided into two groups: torsionally flexible and torsionally rigid.
Flexible couplings, gear couplings, disc couplings from the German manufacturer RINGFEDER (formerly TSCHAN)
Hydrodynamic couplings, elastic couplings, gear and disc couplings and special shaft couplings from the German manufacturer KWD Kupplungswerk Dresden
Elastic couplings, zero backlash couplings, gear couplings, disc couplings from the Italian manufacturer SIT
