A hydrodynamic bearing constructed for withstanding varying radial loads has first and second bearing halves arranged on a central axis and encircling a shaft member, each half having an inner bearing face, first and second ends, and first and second sides. A slot of specific construction is formed in the bearing face of at least one of the bearing halves providing a fluid trap for reducing cavitation erosion during use.
