The bearing housing-base assembly is shown in the figure. The bearing housing 3 is shrink fitted into the base 4 with a tightly controlled interference. This interference allows very reliable control of the holding force and eliminates the possibility of shift of the housing 3 in any direction. In addition, shrink fitting housing 3 increases the stiffness and the natural frequency of the base-housing assembly.
