摘要:
In an embodiment, a bearing apparatus includes a first bearing assembly including a plurality of first superhard bearing elements. The bearing apparatus further includes a second bearing assembly including a plurality of second superhard bearing elements generally opposing and bearing against the plurality of first superhard bearing elements of the first bearing assembly during operation. A support ring carries the plurality of second superhard bearing elements that are distributed circumferentially about an axis. More than one of the plurality of second superhard bearing elements includes an outer convex peripheral surface that is substantially cylindrical and exhibits a convex curvature, and a cutout at least partially defined by a concave peripheral surface that is substantially cylindrical and curved to generally correspond to the convex curvature of the outer convex peripheral surface. The cutout receives an adjacent one of the plurality of superhard bearing elements.
