Abstract

Bearing assemblies, apparatuses, and motor assemblies using the same are disclosed. In an embodiment, a bearing assembly may include a plurality of superhard bearing elements distributed circumferentially about an axis. Each of the superhard bearing elements may include a bearing surface. At least one of the plurality of superhard bearing elements may include at least one texture feature that may be formed in a lateral surface thereof. The bearing assembly may also include a support ring that carries the superhard bearing elements.
