A rolling bearing has a first ring, a second ring concentric with the first ring, and a plurality of rolling elements disposed between the first and second rings, the first ring and the second ring both being generally annular and having gaps therein. A rotating mechanism has a support structure, a rotating structure, and a rolling bearing as described herein mounted on the support structure and engaging the rotating structure. A rotating mechanism having a CTE and a non-split ring bearing having a bearing CTE that is significantly less than the mechanism CTE can be improved by replacing the non-split ring bearing with a bearing having a similar CTE and a gap in the inner ring and in the outer ring.
