RODOFLEX flexible couplings are used in CNC machine tools, both for coupling motion controlle devices and for effective power transmission. The couplings’s flexible element is the metallic bellows which can tolerate angular and parallel misalignment, compression and traction, while remaining torsionally stiff. The torsional stiffness is the most important feature of the RODOFLEX flexible couplings; there are no clearance, back-lash or position transmission errors. The metallic bellows being the flexible element, the construction is compact and lightweight. It has a good mass/torque ratio and therefore a limited moment of inertia, which is useful in applications with high acceleration, rotation sense reversal and high rotation speed. Beside the standard production range presented in this catalogue, manufacturing of special units may be accomplished.
