The Roba-dx bellows couplings are manufactured by Mayr GmbH, Germany, using state-of-the-art technology. These steel bellows couplings are backlash-free, torsionally stiff couplings which can accommodate angular, radial, and axial misalignments which invariably exist between two rotating shafts. These couplings come with either taper cone bushing or clamping hubs to give a perfect zero backlash transmission.
