Abstract:
1. A rolling bearing comprising: at least one outer ring formed by bearing steel; at least one inner ring formed by bearing steel; and rolling elements formed by bearing steel, wherein a phosphorus-based modified layer is formed on at least one surface among a raceway surface of said outer ring, a raceway surface of said inner ring and surfaces of said rolling elements; wherein: said rolling elements are balls, said balls are supported at one point on one of said raceway surface of said outer ring and said raceway surface of said inner ring, and said balls are supported at two points on the other of said raceway surface of said outer ring and said raceway surface of said inner ring; and said rolling bearing is adapted to be used when a load is less than or equal to 0.05 as calculated in terms of Pr/Cr supposing that a dynamic equivalent radial load is Pr and a basic dynamic rated load is Cr, either one of said inner ring and said outer ring is a driving ring, and a sliding speed of said rolling elements with respect to said driving ring is V, said V is higher than 70 m/s.
