Abstract: A bearing system is provided in one example embodiment and may include an inner bearing assembly comprising a spherical bearing and an outer race; an outer bearing assembly comprising a plurality of cylindrical roller bearings, an inner race, and an outer race; and a race element comprising an inner surface and an outer surface, wherein the outer surface of the race element is the inner race for the outer bearing assembly and the inner surface of the race element is associated with the outer race for the inner bearing assembly. The inner bearing assembly allows tilting movements of the bearing system and the outer bearing assembly allows rotational movements and supports, at least in part, radial loads for the bearing system.
