An overhead crane having an adjustable bearing assembly to adjust a wheel a nd axle of the crane in a horizontal direction in order to minimize skewing of the crane on a pair of parallel rails. A bearing retainer includes an outer surface sized t o fit into an associated bore in an end truck of the crane, and an eccentric inner surface which engages the outer surface of a bearing. When the bearing retainer is rotated, the wheel and axle extending therethrough are moved in a horizontal direction. The bearing retainer includes a closed end having a surface which is engageable by a tool to allow for the rotation of the bearing retainer. A locking ring releasably fixes the bearing retainer and therefore the bearing to the frame of the crane as desired.
