LOCKING ASSEMBLIES RfN 7012
These are the original Ringfeder® Locking Assemblies featuring double-tapered thrust rings with self-releasing tapers. They bridge relatively large fit clearances, are easy to install, adjust or remove, but are not self-centering. A pre-centering hub section is usually required.

These units are most commonly used on applications in general engineering to transmit high torques and axial loads utilizing larger machining tolerances.

LOCKING ASSEMBLIES RfN 7013
These locking assemblies are of single-taper design with a self-locking taper providing good self-centering action and concentricity, as well as increased torque capacity. A pre-centering hub section is not required. Integral push-off screws for disassembly are provided. These assemblies are available in two types:

Flange type units fix the hub positively against their extended flange preventing axial movement during tightening.

Applied wherever self-centering action and good concentricity of mounted components is essential and hubs with straight-thru bores are used.
