RINGFEDER® Locking Elements are the most wear- and maintenance-friendly, space-saving and cost-effective design of a friction-locked shaft-hub connection. Derived initially from the proven friction spring technology, our locking elements consist of an outer and an inner taper ring, which interact to create a mechanical connection between the shaft and the component being mounted. The tensioning of the locking elements is carried out by a suitable customer design of hub and shaft. Our powerful, high-precision RINGFEDER® Locking Elements of the RfN 8006 series are available in solid and, for lower required clamping forces, slit types. They are extremely flexible in design and can therefore be ideally adapted to a wide range of applications requiring reliable transmission of low to medium torques and axial loads.
