TAPERED ROLLER BEARING AND MOUNTING STRUCTURE THEREOF

摘要

A tapered roller bearing (1) includes an outer race (5). The outer race (5) is formed by pressing a steel plate, instead of conventional turning, to reduce the manufacturing cost of the outer race (5). The outer race (5) includes a flange portion (11) provided at the large-diameter end of the outer race (5), and a cylindrical portion (12) provided at the small-diameter end of the outer race (5). The flange portion (11) and the cylindrical portion (12) of the outer race (5) are brought into engagement with a housing having an inner peripheral surface corresponding in shape to the outer peripheral surface of the outer race (5) so that the tapered roller bearing (1) can be easily mounted to the housing (2).
