Diamond bearings and bearing components are disclosed. Some embodiments of the bearings and bearing components (127) include polycrystalline diamond compacts (37) sintered under high pressure and high temperature to create a diamond table chemically and mechanically bonded to a substrate (35), the diamond table presenting a durable and thermally stable load bearing and articulation surface.
