Abstract
A bearing assembly for a downhole drilling motor can include a housing having an inner wall, an outer bearing race within the housing, and an inner bearing race. The outer bearing race can include a reduced-diameter portion forming a gap between the outer bearing race and the inner wall of the housing to allow for radial displacement of the outer bearing race relative to the housing. The design combines the functions of a bearing and a compliant feature into a single unit.
