Rolling bearing, rolling device, and method of manufacturing rolling device

A rolling device comprising:

• a first rolling component made of high carbon chromium bearing steel;
• and
• a second rolling component made of high carbon chromium bearing steel and configured to contact the first rolling component,
• wherein a surface of a rolling part of the first rolling component is greater in arithmetic mean roughness than a surface of a rolling part of the second rolling component, and the arithmetic mean roughness of the surface of the rolling part of the first rolling component is 0.70 μm or less,
• wherein the arithmetic mean roughness of the surface of the rolling part of the second rolling component is 0.07 μm or more and 0.20 μm or less, and a root mean square slope of the surface of the rolling part of the second rolling component being 0.074 or more and 0.100 or less,
• wherein the rolling part of the first rolling component is lower in Rockwell hardness than the rolling part of the second rolling component, and the Rockwell hardness of the rolling part of the second rolling component being 61.5 HRC or more,
• wherein a film containing at least one of an iron oxide or an iron compound is provided on the surface of the rolling part of the first rolling component, and
• wherein a value of an oil film parameter in a region between the first rolling component and the second rolling component is 1.2 or less.
