    RfN 7012

    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. Available sizes: metric series for shafts from 16 mm to 1000 mm dia.; Inch series for shafts from 3/4” to 7.875” diameter.

    RfN 7013.0

    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. This unit can be placed deep inside a bore due to it’s design. Available sizes: Metric series shafts from 20 mm to 150 mm dia. and Inch series for shafts from 1” to 4” diameter.

    RfN 7013.1

    These 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 are essential and hubs with straight-thru bores are used. Available sizes: Metric series shafts from 20 mm to 150 mm dia. and Inch series for shafts from 1” to 4” diameter.

  • RfN 7014

    RfN 7014

    This locking device, dual tapered similar the 7012 type, is designed to transmit extremely high torques. Unlike the 7012 style, the 7014 device offers good centering ability due to it’s relatively long design, making a pre-centering hub section unnecessary. It’s design also provides for a different inside diameter to outside diameter ration, thereby not interchangeable with the other RINGFEDER types. Available in sizes from 70 to 200 mm.

    RfN 7515

    Especially for the bending moment transmission designed 3 part Locking Assembly with reduced stresses in the Locking Assembly itself.

    Special Features - Through the long and flat cones one Locking Assembly RfN 7515 can transmit torques and axial forces and bending loads. At mounting is a small axial movement from Locking Assembly and hub.

    Bending moment and radial loads – combined loads can be transmitted (Please contact our specialists for assistance).

    Excellent centering ability – with a relatively wide design.

    Example applications: Belt drums, gear wheels
