Claim 10:
11. A bearing assembly comprising:
an annular housing having a central axis, a first axial end and a second axial end spaced apart along the central axis, and an annular recess extending axially inwardly from the first axial end and circumferentially about the central axis;
a bearing inner ring disposed within the annular recess of the housing and having an inner raceway;
a bearing outer ring disposed about the inner ring and within the annular recess of the housing, 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;
at least one compressible 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 the first set of rolling elements and a preload within the second set of rolling elements; and
a retainer connected with the housing and configured to retain the at least one biasing member within the annular recess of the housing.
