RfN 8006 solid

RfN 8006 solid

Locking Elements consist of an internal and external tapered ring. When axial force is exerted on a set of Locking Elements, radial clamping pressures are generated on the shaft and in the hub bore providing a frictional connection. Units may be stacked up to three Elements deep for greater torques. For light to medium duty applications.

The slit versions are useful in applications requiring the bridging of bigger tolerances and/or higher torques. Stacking of the Elements is not recommended.
