• an outer circumferential surface;
• an inner circumferential surface;
• and
• a second lubricant storage groove extending in an axial direction, the second lubricant storage groove provided on the outer circumferential surface of the cage or the inner circumferential surface of the cage between the first and second pockets, the second lubricant storage groove extending over more than half an axial width of the cage, the axial width extending in the axial direction;
• wherein the first pocket includes a side wall and a first claw extending from the side wall toward a radially inner side or a radially outer side of the cage for holding the first rolling element of the bearing after the first rolling element is assembled in the first pocket, the first claw of the first pocket having an axial end face, the first lubricant guiding groove being provided on the axial end face of the first claw of the first pocket.
