RINGFEDER GWB AKD METAL BELLOWS COUPLING

Ringfeder GWB AKD Metal Bellows Couplings

Ringfeder GWB'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.

Backlash-free Ringfeder GWB AKD Metal Bellows Couplings are used in the sector of mechanical engineering, where a torque or a rotary motion has to be transmitted from shaft to shaft in highest accuracy of angle: Encoder, Pumps with axial and vertical drives, High dynamic portal drives, Spindle lifting units, Linear units, Packaging machines, Machine tools, Special machines.
