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

Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include superhard contact elements. At least some of the superhard contact elements may be configured to remain in contact with each other when a rotational force and/or a thrust force is applied between the assemblies.

Force coupling assemblies and related systems and methods

Bearing assemblies, apparatuses, systems, and methods include bearing assemblies with bearing elements that are at least partially contained in the bearing assembly.

Contained bearing assemblies and related systems and methods

Bearing assemblies, apparatuses, systems, and methods include bearing assemblies with bearing elements configured to accommodate axial movement.

Bearing assemblies configured to accommodate axial movement and related systems and 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.

Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include superhard contact elements. At least some of the superhard contact elements may be configured to remain in contact with each other when a force is applied between the assemblies.
