Lenze Couplings

Torsionally Rigid Steel Disc Couplings

The steel multiple-disc clutches are torsionally stiff and backlash free couplings that are maintenance free and suitable for use in the harshest of environments. These allow for shaft mis-alignments to be compensated but without any damping properties.
