Abstract
A spindle assembly has a shaft with at least two axially spaced expandable shaft sections. The expandable shaft sections serve to couple the spindle to a bearing assembly having inner races. The expandable shaft sections are expanded elastically and uniformly into retentive contact with the inner races to provide radial and axial support for the spindle assembly.
