    • An axial rolling bearing (1) including a cage (6) which contains rolling bodies (7) and which is arranged between two running disks (2, 3) is provided, wherein the running disks (2, 3) have in each case one radial section (4, 5) which forms a raceway and in each case one axially aligned radially outer rim (8, 9) which adjoins the radial section (4, 5), which rim (8, 9) and radial section (4, 5) overlap in the axial direction. The radially outer running disk (3) has a larger diameter than the radially inner running disk (2), and at least the radially inner running disk (2) has a radially inner axially extending rim which adjoins the radial section (4) which forms the raceway. In order to be able to adjust the throughflow quantity of lubricant through the axial rolling bearing in a targeted fashion, it is provided that the radially inner rim (10) of the inner running disk (2) extends axially outward and is elongated so as to form a flange (11). The cage (6) has a radially outer section (12) which is supported against the radially outer rim (8) of the radially inner running disk (2), and the cage (6) has a radially inner section (13) which is angled so as to form an axially outwardly aligned rim (14). The flange (11) of the radially inner running disk (2) and the rim (14) of the cage (6) are formed to have the same axial direction in order to form a labyrinth seal.
    • 本发明提供一种轴承用滚动轴承(1),其具有包含滚动体(7)的保持架(6),并配置在两个运行盘(2,3)之间,其中,所述运行盘(2,3) 径向部分(4,5),其形成一个滚道,并且在每种情况下一个轴向对准的径向外边缘(8,9),其邻接径向部分(4,5),该边缘(8,9)和径向部分(4) 5)在轴向上重叠。 径向外运行盘(3)具有比径向内运行盘(2)更大的直径,并且至少径向内运行盘(2)具有径向内部轴向延伸的边缘,其邻接径向部分(4),其形成 跑道 为了能够以目标方式通过轴向滚动轴承调节润滑剂的通量,内部运行盘(2)的径向内边缘(10)轴向向外延伸并且是细长的,以便 形成凸缘(11)。 保持架(6)具有径向外部部分(12),该径向外部部分(12)支撑在径向内部运行盘(2)的径向外部边缘(8)上,并且保持架(6)具有径向内部部分(13) 成角度以形成轴向向外对齐的边缘(14)。 径向内部运行盘(2)的凸缘(11)和保持架(6)的边缘(14)形成为具有相同的轴向方向以形成迷宫式密封。
