Abstract
A guide piece projects from an outside surface of a cage bar of a cage so as to make sliding contact with a raceway surface of an outer ring. As the cage rotates, the guide piece operates to guide the rotation of the cage while removing an excess grease on the raceway surface and transferring the excess grease to axially opposite ends of the outer ring. The guide piece is formed with a through-hole extending from an inner periphery of the cage to an edge of the guide piece for supplying the lubricant from the inner periphery side of the cage to the raceway surface.
