2.5 - 3,200 Nm / backlash-free servo laminae coupling

Double-cardanic type (servo laminae coupling)

RADEX-NC DK is the double-cardanic standard series with spacer. This type allows for conformal torque transmission while compensating for axial, radial and angular displacements.

RADEX-NC DK with clamping hubs:

With this type easy to assemble the hub is fastened on the shaft by merely tightening one clamping screw - from size 43 via two clamping screws. Here both frictionally engaged connections without feather keyway and positive-locking connections with feather keyway are available.

RADEX-NC DK with clamping ring hubs:

The two-part, rotationally symmetric taper hubs with external clamping screws ensure good concentric running properties with high speeds.


  • backlash-free servo laminae coupling
