    摘要: Embodiments of present invention relate to a bearing assembly, and a bearing apparatus and motor assembly that employs such a bearing assembly. In one embodiment of the present invention, a bearing assembly comprises a support ring including a plurality of recesses and at least one opening. The bearing assembly further includes a plurality of bearing elements, each of which is positioned generally within a corresponding one of the recesses. At least one of the bearing elements includes at least one groove. At least one retention element may be positioned generally within the at least one opening and adjacent to the at least one groove. Further embodiments of the present invention are directed to a thrust-bearing apparatus, a radial bearing apparatus, and a downhole motor that may utilize any of the disclosed thrust-bearing assemblies and radial bearing assemblies.
