Abstract

The invention relates to an axial angular contact ball bearing (1) which is suitable for mounting a rotary table on machine tools and essentially comprises a monolithic or two-part inner bearing ring (2), an outer bearing ring (2), and a plurality of rolling members (8, 9) that are arranged in several rows (4, 5, 6, 7) next to each other between the bearing rings (2, 3). The bearing surfaces of the rolling members (8, 9) roll at defined pressure angles along several raceways (12, 13, 14, 15) that are disposed next to one another on the external face (10) of the inner bearing ring (2) and the internal face (11) of the outer bearing ring (4). According to the invention, all rolling members (8, 9) of the axial angular contact ball bearing (1) are designed as spherical rollers which have two faces that are symmetrically oblate at the axial end and run parallel to each other in order to be able to place more rolling members (8, 9) between the bearing rings (2, 3) of the axial angular contact ball bearing (1) than in previously known rotary table bearings while the mounting space is the same or nearly the same, and significantly increase the load-bearing capacity of the axial angular contact ball bearing (1).
