A greased lubricated rolling element bearing including an inner ring, an outer ring, a plurality of rolling elements disposed between said rings, and a cage for holding the rolling elements at a predetermined mutual spacing, has a lubricating grease composition present on the surfaces of said rings, said rolling elements and said cage. The cage is coated on at least the parts of its surface that are in sliding contact with said rolling elements, said inner ring or said outer ring, with a solid lubricant containing coating for lowering the running temperature of at least the cage. The solid lubricant containing coating preferably comprises a disulfide and/or diselenide of a Group V or VI transition metal, more preferably MoS.sub.2 and/or WS.sub.2 in combination with an organic resin such as PTFE.
