Abstract

The invention relates to a rolling bearing (8) comprising at least one outer race (9) and a track that is arranged on the inner peripheral surface thereof, and a plurality of rolling elements (3) that are arranged in the outer race (9) along the track at defined distances. The rolling elements (3) are surrounded by a solid lubricant so that they and the solid lubricant (3, 2) form a one-piece unit (1). The rolling bearing (8) according to the invention is characterized in that the one-piece unit (1) is provided with recesses (4, 5) on its inner and/or outer peripheral surface, said recesses being used as reservoirs for an additional lubricant. The lubricating effect of the solid lubricant is substantially improved by the additional lubricant.
