Flange Coup­lings of the RINGFEDER® TNF 5571 type are used to reliably establish an absolutely backlash-free connection between two shafts by means of frictional locking. They are the more powerful and more economic alternative to conventional press fits. For assembly, the flange halves are simply pushed onto the shaft ends and friction-locked by means of shrink discs – the flanges are then also connected using a simple screw connection. Neither additional components such as keyways or wedges nor heating of the inner section or cooling of the outer are are necessary. RINGFEDER® Flange Coup­lings are torsionally rigid and are characterized by high concentricity as well as the admissibility of large shaft tolerances. In addition to highest torques, they also transmit occurring bending loads as well as axial and radial forces without wear and with high precision. Flange couplings of the RINGFEDER® TNF 5571 type are particularly convincing due to the following features: Zero backlash, wear and maintenance Robust connection with high strength reserves Direct power transmission between shaft and flange Highest concentricity Easy mounting and dismounting
