Abstract
A bearing having two surfaces (60, 72) rotatable with respect to each other, a lubrication medium located in a gap between the tow surfaces during rotation of the bearing and a sinusoidal groove pattern (20) formed on one of the tow surfaces to distribute the lubrication medium over the surface of the bearing and create a pressure distribution in the bearing to create a stiff hydrodynamic bearing.
