RINGFEDER® Flange Couplings are the better alternative to press
fits. Neither additional components such as keyways or wedges, nor
a warming of the outer section and cooling of the inner section are
required. The flange coupling is simply pushed onto the shaft and
fastened so it is frictionally engaged by tightening the screws in the
shrink disc. They transfer torque and bending moments as well as
axial and radial forces.
