Abstract: A two-part bearing cage for a ball bearing, including a first and a second annular body (1a, 1b) having a plurality of retaining claws (2) on their opposing end faces. The two annular bodies (1a, 1b) have an identical design and can be mounted opposite each other in such a way that cut-out sections (3) receive the retaining claws (2), thereby forming pockets (4) for receiving and guiding rolling bodies (5). The number of pockets (4) corresponds to the number of rolling bodies (5). According to the invention, the individual pockets (4) are arranged at a distance from one another in the circumferential direction in such a way that a free area (6) for receiving lubricant is formed between two pockets (4). At least two pairs of retaining claws (2), at least two individual retaining claws (2), and the base of a pocket combine to form one pocket (4). The invention also relates to a ball bearing comprising a two-part bearing cage of this type.

Abstract: A plastic rolling bearing cage, namely an angular ball bearing cage, including two cage rings, the diameters of which differ from one another, namely a smaller cage ring and a larger cage ring. A number of cage pockets for accommodating in each case a rolling body, namely a ball, are formed by the cage rings and by the cage webs connecting them. The cage rings are designed in one piece with the cage webs and contain solid lubricant. The ratio of the third power of the width (BKi, BKa) of the cage ring, which is measured in the axial direction, and the cage pocket diameter (DW) is at least 0.4 mm2.
