Bearing assemblies that include a plurality of polycrystalline diamond ('PCD') bearing elements, bearing apparatuses including such bearing assemblies, and methods of operating and fabricating such bearing assemblies and apparatuses are disclosed. In an embodiment, the plurality of PCD bearing elements of one or more of the bearing assemblies disclosed herein include at least one first PCD bearing element. At least a portion of the first PCD bearing element exhibits a coercivity of about 125 Oersteds or more and a specific magnetic saturation of about 14 Gauss cm/gram or less. The first PCD bearing element includes a bearing surface with at least one groove formed therein. In an embodiment, the plurality of PCD bearing elements also include at least one second PCD bearing element. The second PCD bearing element exhibits a coercivity that is less than and a specific magnetic saturation that is greater than the first PCD bearing element.

Bearing assemblies, bearing apparatuses, and related methods

Bearing assemblies, apparatuses, systems, and methods include bearing assemblies where one of the bearing assemblies may include angled bearing surfaces having a planar shape.

Bearing assemblies, apparatuses, and methods including bearing elements

Bearing assemblies, apparatuses, systems, and methods include bearing assemblies where one of the bearing assemblies may include bearing surfaces defining an at least partially conical surface.

Methods of manufacturing a radial sliding bearing may include coupling superhard contact elements to support rings where each superhard contact element includes a superhard contact surface and forming at least some of the superhard contact surfaces to comprise an arcute or a planar surface.

Bearing assemblies and apparatuses and related methods

Radial bearing

A heating apparatus for induction heating is disclosed. The heating apparatus may comprise a bearing ring, at least one bearing element disposed in the bearing ring, and a braze material adjacent to the at least one bearing element and the bearing ring. The heating apparatus may additionally comprise an inductor positioned radially adjacent to at least a portion of the bearing ring. A current source may be electrically coupled to the inductor. A bearing orienting member may also abut a surface of the at least one bearing element. The bearing orienting member may orient a surface of the at least one bearing element. A heating method is also disclosed.

Apparatuses and methods for induction heating

Bearing assemblies, apparatuses, systems, and methods include bearing assemblies where one of the bearing assemblies may include bearing surfaces defining an at least partially conical inner surface.

Load-carrying apparatus, assemblies, and subterranean drilling systems may include a support ring with a plurality of contact elements coupled to the support ring. The plurality of contact elements may have a surface exhibiting a partially cylindrical shape.

Assemblies and apparatuses including superhard elements

Bearing assemblies that include a plurality of polycrystalline diamond ('PCD') bearing elements, bearing apparatuses including such bearing assemblies, and methods of operating and fabricating such bearing assemblies and apparatuses are disclosed.
