The characteristic feature of the Conax® clutch is the expanding symmetrical friction ring* between the cone-shaped metal discs. It is divided into six segments which are held together by a tension spring. Axial displacements of the shafts are offset in the bore of the casing when the clutch is disengaged. The contact forces in the system cancel each other out, there is no axial loading of the machine bearings when the clutch is engaged.
