These shaft clamping elements are very compact units capable of
transmitting medium torques. Their design ensures good concentricity
between hubs and shafts, without any other means of location. A slight
axial movement between hub and shaft occurs during clamping. These
units can be installed totally within the hub providing optimum safety, and
minimal axial length.
Recommended tolerances for full
torque transmission are:Shaft
