A bearing assembly includes an inner ring with an inner raceway and disposable about a first member and an outer ring with an outer raceway disposed about the inner ring. A middle ring is disposed between the inner and outer rings and has an inner intermediate raceway and an outer intermediate raceway and is configured to connect with a second member so as to be rotatable about a central axis through the first member. A first set of rolling elements is disposed between the inner ring and the middle ring and a second set of rolling elements is disposed between the outer ring and the middle ring. The outer ring is sized such that a ratio of the outside diameter to the axial width is greater than eight to one (8:1) and the middle ring is formed of a material different than the inner and outer rings.
