Patent

CA 2737531

Various embodiments relate to bearing assemblies configured to enable removal and replacement of superhard bearing elements, and bearing apparatuses that may utilize such bearing assemblies. The disclosed bearing assemblies may be used in a number of applications, such as downhole motors in subterranean drilling systems, directional drilling systems, roller-cone drill bits, and many other applications. In an embodiment. a bearing assembly includes a support ring and a retention ring assembled with the support ring. The retention ring includes a plurality of through holes. The bearing assembly further includes a plurality of superhard bearing elements, with each superhard bearing element inserted partially through and projecting from a corresponding one of the through holes of the retention ring. The retention ring and each superhard bearing element are collectively configured to restrict displacement of each superhard bearing element beyond a selected position in a direction away from the support ring.
