More Information
Summary:A bearing assembly includes a support ring circumferentially surrounding a central bearing axis and a plurality of superhard bearing elements coupled to the support ring. Each of the plurality of superhard bearing elements has a base, a superhard bearing surface, and a lateral periphery extending between the base and the superhard bearing surface. The superhard bearing surface has a partial-ellipsoidal surface shape. A bearing apparatus includes an inner bearing assembly and an outer bearing assembly. A subterranean drilling system includes an output shaft operably coupled to a bearing apparatus.
