RINGFEDER GWB AKN METAL BELLOWS COUPLING

DESCRIPTION: The metal bellows couplings from the 'AKN' series boast Ringfeder'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.

Backlash-free AKN Metal Bellows Couplings

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

Backlash-free AKN 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.
