Abstract: A stationary thrust bearing is for a stationary and rotating thrust bearing system designed to withstand an axial load along an axis of a rotation shaft mounted in a guide bearing, in particular of a turbocharger. The stationary thrust bearing includes a flange in which is created a through-opening that allows the rotation shaft to pass through and has, on a face, pads with structured regions. Specifically, at least two sets of the pads, which include a first set of pads with structured regions present in a first ring on the face of the flange, and a second set of pads with structured regions present in a second ring, coaxial with the first ring, on the face of the flange, set back relative to the first set of pads in the longitudinal direction of the axis of the opening.
