The heart of the RADEX-N steel laminae coupling are the laminae sets along with their connection to hubs and spacers. The high-strength and special dowel screws are reciprocally screwed to hubs and spacer allowing for a combination of friction and positive-locking fit. In this way our laminae coupling ensures high power density with simultaneous ease of displacement and low restoring forces.
The special design of the components of the RADEX-N laminae coupling allows for prestress of the laminae sets, increasing the torsional stiffness of the all-steel coupling by approx. 30 % and at the same time preventing axial vibrations of the spacer.
This type has been assessed and approved as equipment of category 2G/2D according to EU directive 2014/34/EU and is consequently suitable for use in potentially explosive areas of zones G1, G2, D21 and D22 .
