Medium Duty Locking Assembly RfN 7015-440
Locking Assembly RfN 7015-440 reflects the best in RINGFEDER engineering expertise for its superb centering and high torque transmission.
• Precision Locking Assembly for the transmission of maximum torques and axial forces with special demands on the concentricity of the parts of the clamped, as well as for applications subjected to bending moments.
• Bending moment and radial loads – combined loads can be transmitted.
• Large transmittable peripheral forces – due to the long, flat cones it is possible to transmit maximum torques and axial forces with one RfN 7015.0 Locking Assembly. During installation the Locking Assembly, shaft and hub remain in position to one another. Compared to 3-part versions, thus an additional safety is provided. Shaft and hub are only compression-loaded.
• Excellent centering ability – with a relatively wide design and the precentering web the RfN 7015.0 Locking Assembly has excellent centering ability.
