PROBLEM TO BE SOLVED: To actualize the longer life of a rolling device which has a solid lubricant coat formed on the raceway surface or the rolling surface to bear high speed rotation and high load in the atmosphere.SOLUTION: The rolling device includes an outward member, an inward member, and a rolling element. Onto at least one of the outward member, the inward member, and the rolling element, phosphate treatment is applied as surface preparation. The solid lubricant coat containing two carbon materials is formed thereon. The rate of the carbon materials to the lubricant coat is 80-100 mass%.SELECTED DRAWING: Figure 1 |
