Abstract
A thrust bearing configured to support axial loads that act on a rotating body includes a thrust shaft rotatably supportable in a bearing housing, a thrust collar, and a retainer connected to the thrust shaft and configured to support a plurality of thrust pieces. The thrust pieces each have a front sliding surface in sliding contact with the thrust collar, and the retainer includes a disk having a central opening and an outer circumference and a plurality of radial incisions extending radially inwardly from the outer circumference which incisions have inner ends radially spaced from the central opening. The radial incisions define circumferentially adjacent spring sections each of the which is individually axially flexible against and away from the bearing housing to open and close a spring gap between each of the spring sections and the bearing housing.
