Abstract
An inner ring cooperates with an outer ring to form a roller bearing assembly. The inner ring comprises an outer circumferential surface receiving a plurality of roller bearing elements engageable with the outer ring upon forming of the roller bearing assembly. An inner circumferential surface of the inner ring is slideably mountable to a shaft upon forming of the roller bearing assembly and includes a base portion slideably engageable with a surface of the shaft upon mounting and at least one cutout portion opening to an outer edge of the inner circumferential surface. A clearance forms between a surface of the at least one cutout portion and the surface of the shaft upon mounting. Upon forming of the roller bearing assembly, the base portion of the circumferential surface is engageable with the shaft subsequently to the plurality of roller bearing elements engaging with the outer ring.
