摘要： A thrust needle bearing, comprising a cage formed by pressing a steel sheet. The value of the arithmetic average roughness Ra of rollers (2) is 0.03 to 0.15 mum in a rolling bearing in which a lubricating oil is used and the rollers (2) held by the cage (3) roll on races (1a, 1b). Even when the bearing is used under the conditions where lubrication is lean or lubrication characteristics are wrong, the rolls can be prevented from being worn at the contact parts thereof with the pocket guide face of the cage and the life of the rollers and races can be increased.
