Abstract
There is provided a hub bearing unit with multiple rows of rolling elements. A hub has one or more inner race surfaces. An inner ring is seated on an outer peripheral surface of the hub and has one or more inner race surfaces thereon. An outer ring is formed with outer race surfaces as many as inner race surfaces formed at the hub and the inner ring. Rolling elements are disposed between the outer race surfaces and the inner race surfaces. Cages are disposed to maintain circumferential intervals of the rolling elements. The outer ring is formed with three or more outer race surfaces. The rolling elements are arranged in three or more rows. The arrangement of multiple-row rolling elements enhances the life of the bearing. Manufacturing costs are curtailed and rolling resistance is reduced compared to the tapered roller bearing.
