A system and method is provided to accommodate positional variations in a bearing assembly, which has a clearance adjustment assembly for setting the roller clearance therein. The bearing assembly has multiple rows of tapered rollers disposed circumferentially between an inner sleeve and the clearance adjustment assembly, which is secured by an outer retaining sleeve. The clearance adjustment assembly has at least one clearance adjustment ring disposed adjacent multiple tapered support rings, which extend circumferentially about the multiple rows of tapered rollers. In the bearing assembly, the at least one clearance adjustment ring forces the multiple tapered support rings against the multiple rows of tapered rollers to set the desired roller clearance. Accordingly, the bearing assembly can accommodate expansion, contraction, and angular variations in the system.
