Abstract: A hydrodynamic slide bearing (10, 10?) supports a shaft (14, 14?) that is mounted rotatably. The hydrodynamic slide bearing (10,10?) comprises a plurality of bearing segments (12, 12?) arranged next to one another in the rotation direction (22, 22?). The segment surfaces together form a running surface (16, 16?) for the shaft (14, 14?). At least one bearing segment (12, 12?) has a plurality of grooves (26, 26?) disposed in its segment surface, and the grooves (26, 26?) are orientated substantially transverse to the rotation direction (22, 22?). The rear groove edges (261) in the rotation direction (22, 22?) are orientated obliquely to their respective assigned radial plane (24, 24?) and are undercut in relation to their respective assigned radial plane (24, 24?). The front groove edges (262) in the rotation direction (22, 22?) are not undercut and are orientated obliquely to their respective assigned radial plane (24, 24?).
