Zusammenfassung: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 bearing assembly further includes a plurality of superhard bearing elements. The retention ring and at least a number of the superhard bearing element are collectively configured to restrict displacement of the at least a number of the superhard bearing elements.
