PROBLEM TO BE SOLVED: To provide a rolling bearing and other rolling devices, excellent in fatigue life, wear resistance, corrosion resistance, acoustic characteristic, etc., by considering the relationship between carbon and nitrogen in the composition of a bearing material and other composition relations. SOLUTION: At least one among an outer member (outer ring) 1, an inner member (inner ring) 2, and a rolling element 3 is composed of stainless steel which has a composition consisting of, by weight, <0.6% C, 10.0-22.0% Cr, 0.1-1.5% Mn, 0.1-2.0% Si, 0.05-<0.2% N, and the balance Fe with inevitable components and further satisfying 0.04Cr%-0.83N%-0.39<=C%<=-0.05Cr%+1.41 and C%+N%>=0.45%. |
