ABSTRACT:
A diamond thrust bearing and method for manufacturing the diamond thrust bearing wherein diamond bearing pads are interference fitted at ambient temperatures into a plurality of equidistantly spaced bearing pad recesses located in a circle in a receiving surface of a bearing pad retainer. The bearing faces of the diamond bearing pads are located coplanar with a predetermined common bearing plane by pressing the bearing faces into the bearing pad retainer with a ram and inflexible pressing plate until the pressing face of the pressing plate is stopped by a press stop block. The diamond thrust bearing manufactured using the method will be free from heat induced stresses that cause bearing face misalignment.
