The present subject matter is directed to a bearing assembly for a wind turbine. The bearing assembly includes an outer race, an inner race rotatable relative to the outer race, a plurality of rolling elements positioned between the inner and outer races, and a cage assembly configured to maintain separation between neighboring rolling elements. The cage assembly includes a plurality of cage elements and a plurality of spacers. Each of the cage elements are separated by at least one of the spacers. Further, each of the cage elements extends around at least a portion of the plurality of rolling elements. Moreover, at least one of the spacers contact one or more of the rolling elements.
