The production series 'AKD' offers the traditional metal bellows coupling which can be used for a wide range of applications. Its core characteristics are the backlash-free transmission of torque, high torsional stiffness, and excellent compensation of angular, axial and radial misalignments. Operational safety and easy assembly are two more factors speaking in favour of AKD.
