Abstract

The invention relates to an axial bearing, in particular a clutch release bearing. The aim of the invention is to provide solutions which permit the production of an axial bearing that is particularly suitable for use as a clutch release bearing, is cost-effective to produce in terms of commercial manufacture and has a long service life. The aim is achieved by an axial bearing comprising a first bearing race (1) that is designed as a flat annular disc, a second bearing race (2) that is likewise designed as a flat annular disc, rolling bodies (W) that are held in a defined space (B) between the first bearing race and the second bearing race and a cage unit (3) for guiding the rolling bodies within the space. The axial bearing is characterised in that a first race strut (1a) is formed on the outer peripheral region of the first bearing race and a second race strut (2a) is likewise formed on the outer peripheral region of the second bearing race, both race struts (1, 2) being radially offset and dimensioned in relation to one another in such a way that they overlap in a peripheral region around the edge of the space (B), forming a running gap (S). This permits the advantageous production of an axial bearing that is particularly suitable for use as a clutch release bearing, that has an extremely low axial installation depth and in which the rolling body space that holds the rolling bodies is encapsulated in an especially effective manner.
