Abstract
A calcium zinc phosphate-type coating is formed on at least one of those surfaces of an inner ring, an outer ring and rolling elements (balls) and further a cage (if the cage is used) (which form a touchdown bearing) contacting other members, and further a molybdenum disulfide coating is formed thereon. By doing so, the adhesion of the molybdenum disulfide coating is enhanced by microscopic pits and projections due to crystal grains on the surface of the calcium zinc phosphate-type coating, and also even when the molybdenum disulfide coating is worn out, the wearing-out of a substrate can be suppressed by the lubricating ability of the calcium zinc phosphate-type coating underlying it.
