Abstract
A shaft assembly includes a shaft with a first radial shoulder and a second radial shoulder. The first radial shoulder and the second radial shoulder each include at least one slot. An axial separation between the first radial shoulder and the second radial shoulder defines an axial distance SA along an axis of rotation. The at least one slot defines a lowermost radial dimension SR from the axis of rotation. A ratio of SR/SA is 0.25-0.77.
