Abstract
An axial rolling bearing includes a cage having pockets for retaining rolling elements between two plane-parallel bearing disks for forming a structural unit through interlocking engagement. At least one bearing disk exhibits a peripheral edge which is turned in to form an axial collar which surrounds the cage with clearance and extends towards a radial plane of the other bearing disk to form at least one annular gap. The cage is provided in an area of the annular gap with through-bores which are radially spaced from the pockets and are defined by a diameter, with the annular gap having a radial dimension which is equal or greater than the diameter of the through-bores.

An axial rolling bearing, comprising a cage having pockets for retaining rolling elements between two plane-parallel bearing disks, with the cage forming with the rolling elements and the bearing disks a structural unit through interlocking engagement, wherein at least a first one of said bearing disks exhibits a peripheral edge which is turned in to form an axial collar that surrounds the cage with clearance and extends towards a radial plane of the second one of the bearing disks to form at least one annular gap defined by a radial dimension, said cage being formed in an area of the annular gap with through-bores which are radially spaced from the pockets and are defined by a diameter, wherein the annular gap has a radial dimension which at least equals the diameter of the through-bores.
