Description: Rotex Torsionally Flexible Couplings are small in dimensions, light weight and have light mass moments of inertia yet transmit high torques. Rotex couplings are torsionally flexible and designed for positive torque transmission. The operational vibrations and shocks are efficiently dampened and reduced. The teeth of the spider are crowned to prevent edge pressure if the shafts are misaligned. Rotex couplings can be replaced for axial, radial and angular displacements of the shafts to be connected. The maximum torsion angle with Rotex couplings of any size amounts to 5?. These couplings can be fitted both horizontally and vertically.
