• EKN

    EKN

    GERWAH's 'EKN miniatur' is a backlash-free metal bellows coupling which boasts a very compact shape. The miniature coupling is connected to the shaft by means of radial set screws instead of a clamping hub. The element can be used in many different areas and displays all its advantages when misalignments between driver and driven components have to be compensated.

  • PKN

    PKN

    GERWAH's 'PKN' unites the tried and tested technical advantages of a metal bellows coupling and a plug-in connection. These elements do not need any axial initial load due to tightening and thus allow for easy mounting and disassembly. The PKN series is the perfect choice when power has to be transmitted from shaft to shaft with the greatest possible angular accuracy.

  • AKN

    AKN

    The metal bellows couplings from the 'AKN' series boast GERWAH's trusted quality and increased torsional stiffness. The reduced shafts in the element guarantee for high stiffness while at the same time compensating angular, axial and radial misalignments. The shaft connection is established by means of clamping hubs on both sides.

  • AKD

    AKD

    GERWAH's 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.

  • AK

    AK

    Metal bellows couplings from the 'AK' series have been designed especially for the backlash-free transmission of high torques of up to 5,000 Nm. The elements are mounted on driver and driven components with tapered clamping bushings. Depending on the required size, the coupling will be produced with hubs made of aluminum or stainless steel. In addition, AK guarantees for perfect concentric running.
