Abstract: Apparatuses and methods are provided for manufacturing bearing assemblies. In accordance with one embodiment, a fixture is provided for use in brazing bearing elements to a bearing ring. The fixture comprises a substantially annular body and at least one or more force-applying mechanism associated with the annular body. The force applying mechanisms include a push rod disposed within a channel that is formed in the annular body, the push rod being displaceable within the channel. A biasing member is configured to bias the push rod in a radial direction relative to the annular body. In one embodiment, a plurality of force-applying mechanisms are circumferentially spaced about the substantially annular body. In one embodiment, the push rods extend radially inwardly from a peripheral surface of the body, while in another embodiment the push rods extend radially outwardly from peripheral surface of the body.

Abstract: Bearing components, bearing assemblies and related methods are provided. In one embodiment, a bearing element includes a base layer and a polycrystalline diamond (PCD) layer comprising a plurality of PCD elements coupled with the base layer wherein each PCD element comprising a substrate and a diamond table. The plurality of PCD elements may be fit together to form a substantially continuous bearing surface. For example, the diamond tables may exhibit substantially square or rectangular geometries that are fit together to define the bearing surface. In other embodiments, the bearing elements may be spaced apart from one another. In other embodiments, the bearing element may include a single PCD element formed from a prefabricated PCD compact or cutting tool blank. Various bearing assemblies may incorporate such a bearing element including, for example, thrust bearings, journal bearings, and tilting pad bearing assemblies.
