Patent number: 8360652Abstract: 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.Type: GrantFiled: October 10, 2007Date of Patent: January 29, 2013Assignee: IL Jin Global Co., Ltd.Inventors: Jong Soon Im, Won Rak Bae, Ju Sang Park

Patent number: 7617610Abstract: The present invention relates to a method of measuring a clearance of a hub bearing for vehicles. A hub is fixed to a lower jig when a row of hub-side balls is disposed and an outer ring is disposed on an outer periphery of the hub and a row of inner ring-side balls and an inner ring are disposed. A press-fit jig is contacted to the inner ring and a load of less than 5 kgf is applied to an outer surface of the outer ring to prevent its vibration and movement. A gauge is installed to a portion of the outer ring. The inner ring is gradually press-fitted by the jig. An amount of press-fit of the inner ring is measured from when the gauge begins to move when press-fitting of the inner ring is completed. The amount of clearance is simply measured.Type: GrantFiled: May 29, 2007Date of Patent: November 17, 2009Assignee: Il Jin Global Co., LtdInventors: Young Su Song, Suk Yong Bae
