<p>PROBLEM TO BE SOLVED: To provide a shell-type roller bearing which enhances a degree of freedom in design of an inside diameter of a flange part, also enhances the rigidity of an outer ring, and can discriminate a direction.SOLUTION: A shell-type roller bearing (10) comprises: a shell-type outer ring (11) including a flank part (12), a first flange part (13) and a second flange part (14); and rollers (15) which are arranged along an inside diameter face (12a) of the shell-type outer ring (11). The first flange part (13) is continuous to the flank part (12), and extends to an inside diameter side from one end part of the flank part (12). The second flange part (14) is continuous to the flank part (12), and extends to the inside diameter side from the other end part of the flank part (12). The first flange part (13) is formed into a shape having a flat outside face (13a), and the second flange part (14) is formed into a shape having a ring-shaped step part (14a).</p> |
