    A bearing assembly for rotatabiy supporting a shaft member. The bearing assembly has an inner ring having an Loner. surface sized to receive the shaft member therein. A first fastener threadedly engages a first fastener aperture formed in the inner ring such Ihat a distal end of the first fastener engages the shaft member to selectively retain the inner ring to the shaft member for rota -. tion therewith. A first groove extends along the inner surface of the inner ring and is aligned with the first fastener aperture formed in the inner ring. The first groove is sized to permit clearance between a burr or other obstruction formed on an exterior surface of the shaft member.
