| description | 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 1 a of inner ring 1 and a raceway surface 2 a 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 1 a of inner ring 1 , raceway surface 2 a of outer ring 2 , and a rolling contact surface 3 a of rolling element 3 . The thickness of the lubricant film is preferably 0.05 mum or more and 8 mum or less. |
