PROBLEM TO BE SOLVED: To provide a double-row angular bearing having an improved rolling life and reduced costs. SOLUTION: The double-row angular bearing comprises inner rings 24A, 24B having inside rolling surfaces 28, 29 on the outer diameter faces, respectively, an outer ring 25 having outside rolling surfaces 26, 27 on the inner diameter face, and rolling elements 30 rollingly stored between each of the outside rolling surfaces 26, 27 of the outer ring 25 and each of the inside rolling surfaces 28, 29 of the inner rings 24A, 24B. At least one of the outer ring 25 and the inner ring 24 is molded into a plastic product with cold rolling using martensitic stainless steel. COPYRIGHT: (C)2009,JPO&INPIT
