Abstract

The invention relates to a hydrodynamic bearing, namely a hydrodynamic disk-shaped thrust bearing or hydrodynamic thrust washer, wherein hydrodynamic structures having elevations and having depressions arranged between adjacent elevations are arranged on opposite sides of the bearing, which hydrodynamic structures extend in the peripheral direction, and slopes of the hydrodynamic structures are arranged between adjacent depressions, which slopes extend from the depressions toward the elevations. According to the invention, at least some of the elevations of the hydrodynamic structures of the first side of the bearing are arranged in the region between two depressions of the hydrodynamic structures of the second side of the bearing, the elevations of a side of the bearing being arranged at an offset to each other in the peripheral direction.
