Abstract

PURPOSE: To improve lubricating efficiency and to prevent wear and seizure by forming a plurality of projecting portions on the inside surface side of the bottom wall of a bearing outer ring and effectively introducing the grease on the wall in between the contact surfaces.
CONSTITUTION: The flat portion of the inside surface of a bottom wall 41 is formed with a plurality of projecting portions 46 each having a top portion in the shape of a curved surface or mount and an arbitrary plan shape, the top portion in sliding contact with a mating part during use. Even when the top portions of the projecting portions 46 are worn or deformed by face pressure, leading to face contact, the contact area will be as small as nearly that of point contact, so that the grease around the projecting portions 46 can be effectively introduced in between the contact surfaces. Therefore, the contact surfaces are lubricated effectively, heat generation, seizure, local wear, and the like due to insufficient lubrication rarely occur, and the bearing can be used for a long period of time.
