A tubular portion of the adaptor has a non-cylindrical outer surface to be received within an inner bearing ring bore and a non-cylindrical inner surface to receive a non-cylindrical shaft. Flanges are directed substantially radially outwardly from the tubular portion at the adaptor ends to engage the end surfaces of the inner bearing ring. Slots distributed along the perimeter of at least one adaptor end and extending longitudinally through the flange and part of the tubular portion form a plurality of retention fingers. The retention fingers may bend radially inwardly and outwardly to permit insertion into the inner bearing ring and to accommodate dimensional variation of the non-cylindrical bore and the non-cylindrical shaft.
