ROBA®-DS - The torsionally rigid servo coupling

ROBA-DS couplings are shaft connections and transmit torsionally stiff and backlash-free torque. At the same time, they compensate for angular and axial misalignments in single-jointed couplings (Type 950._ _ _) and radial misalignments in
double-jointed couplings (Type 951._ _ _).
