RINGFEDER FLANGE COUPLINGS RFN 5571 - VERSION B
DESCRIPTION: RINGFEDER Flange Couplings RfN 5571 are the better alternative to press fits. 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.
