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.
INCH SIZES for shafts
from 3/4" to 7.875" dia.
METRIC SERIES for shafts from 20 mm to 1000 mm dia.
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:
Straight-thru Type: RfN
Flange Type: RfN
Flange type units
fix the hub positively against their extended flange preventing axial
movement during tightening.
self-centering action and good concentricity of mounted components
is essential and hubs with straight-thru bores are used.
INCH SIZES for shafts from 1" to 4" dia.
METRIC SERIES for shafts from 20 mm to 150 mm dia.
