| Abstract | Generally-speaking, passenger cars use double-row angular contact ball bearing hub units as wheel bearings, while heavy vehicles such as a sport utility vehicles (SUV) and pickup trucks use a pair of tapered roller bearings (TRB) or 1st or 2nd generation double-row TRB hub units. Recently, there is an increased demand for 2.5th and 3rd generation double-row TRB hub units with integrated hub shafts, particularly for front wheel application. This report describes the characteristics and design points of the 2.5th generation double-row TRB hub unit, which is gradually becoming a main product in SUVs and pickup trucks. |
