Claim 0:
1. A bearing assembly for movably coupling a first member and a second member and disposed within an annular space at least partially defined by a housing having a central axis, the bearing assembly comprising:
a bearing inner ring disposed within the annular space and having an inner raceway;
a bearing outer ring disposed about the inner ring and within the annular space, the bearing outer ring having an outer raceway;
at least one bearing intermediate ring disposed radially between the bearing inner ring and the bearing outer ring and having an inner intermediate raceway and an outer intermediate raceway;
a first set of rolling elements disposed between the bearing inner ring and the at least one bearing intermediate ring so as to be rollable along the inner raceway and the inner intermediate raceway;
a second set of rolling elements disposed between the bearing outer ring and the at least one bearing intermediate ring so as to be rollable along the outer raceway and the outer intermediate raceway; and
at least one biasing member configured to bias a movable one of the bearing inner ring and the bearing outer ring generally axially toward the other one of the bearing inner ring and the bearing outer ring so as to establish a preload within at least one of the first set of rolling elements and the second set of rolling elements,
wherein the housing includes an annular body having a first axial end, an opposing second axial end and an annular recess extending axially inwardly from the first axial end toward the second axial end, the annular recess defining the annular space.
