摘要:
A rolling device in which damage such as seizure or wear is less liable to occur and which has a long life, even when used under severe conditions such as high speed, heavy load, high temperature and insufficient lubrication. A thrust needle roller bearing includes an inner ring 1, outer ring 2, and a plurality of rolling elements 3 rollably arranged between a raceway surface 1a of inner ring 1 and a raceway surface 2a of outer ring 2. A lubricant film consisting of a solid lubricant is coated over an area equivalent to an area ratio of 75% or more of at least one member of the group consisting of raceway surface 1a of inner ring 1, raceway surface 2a of outer ring 2, and a rolling contact surface 3a of rolling element 3. The thickness of the lubricant film is preferably 0.05 μm or more and 8 μm or less.
