Zusammenfassung:	A bearing having two surfaces (60, 72) rotatable with respect to each other, a lubrication medium located in a gap between the two surfaces during rotation of the bearing and a sinusoidal groove pattern (20) formed on one of the two 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. Palier présentant deux surfaces (60, 72) rotatives l'une par rapport à l'autre, un milieu lubrifiant prévu dans une fente ménagée entre les deux surfaces au cours de la rotation du palier ainsi qu'un motif de gorges sinusoïdales (20) formé sur l'une des deux surfaces pour répartir le lubrifiant sur la surface du palier et entraîner une distribution de pression dans le palier qui permet d'obtenir un palier hydrodynamique rigide.
