In a hydrodynamic axial bearing (10), a rotating body (13) is mounted radially in a radial bearing (17) of a bearing body (18). The rotating body (13) comprises a shaft (16), with its shaft journal (14) mounted in the radial bearing (17), and a bearing collar (20) which is connected fixedly to the shaft (16) and corotates with the shaft (16). A floating disk (12) is arranged in an annular-groove-shaped space (28) between a wall (26) of the fixed bearing body (18) and a projection (22) of the corotating bearing collar (20). The floating disk (12) has a central circular orifice (30) which is designed as an integrated hydrodynamic radial bearing (32). By means of this radial bearing (32), the floating disk (12) is mounted radially on a fixed bearing element (38) concentrically surrounding the rotating body (13) on a portion (29).
A hydrodynamic axial bearing with a bearing body, with a rotating body mounted in a radial bearing of the bearing body and having a corotating projection, and with a floating disk which is arranged in an annular-groove-shaped space between the projection and a wall of a fixed bearing body and is mounted radially via a hydrodynamic radial bearing, wherein the floating disk is mounted radially via the hydrodynamic radial bearing on a fixed bearing element which concentrically surrounds the rotating body on a portion, so that an uncoupling gap is formed in the portion between the fixed bearing element and the rotating body.
