Metal Bellows Couplings GWB AKN

The metal bellows couplings from the 'AKN' series boast 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.
