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 and methods of using bearings are provided in the present disclosure. In one embodiment, a bearing ring is provided having a plurality of carrier components removably coupled therewith. Each carrier component may carry one or more bearing elements. Upon wearing of the bearing elements beyond a desired amount, the carrier components may be removed from the bearing ring and installed in a different bearing ring to place the mearing elements at their original bearing surface radius. In another embodiment, individual bearing elements may be radially adjustable relative to the bearing ring to define and redefine the radius of a radial bearing surface.

Adjustable bearing assemblies and related apparatus 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 and methods of manufacturing bearing assemblies are provided in the present disclosure. In one embodiment, a bearing assembly includes a base member and at least one bearing element coupled to the base member. The bearing element may be coupled with the base member by at least two different coupling techniques, including two of: a mechanical fastener, a clamped structure, a geometrical fit, welding, and brazing. In one embodiment, a first technique may include use of a mechanical fastener and a second technique may include welding or brazing. In another embodiment, a first technique may include use of a clamping mechanism or structure and a second technique may include welding or brazing. In another embodiment, a first technique may include use of a geometrical fit and a second technique may include welding or brazing.

Attachment of PDC bearing members, bearing assemblies incorporating same 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 force is applied between the assemblies.

Torque coupling assemblies and related systems and methods

Embodiments disclosed herein relate to bearing assemblies and methods of manufacturing. In an embodiment, a bearing assembly includes a support ring and bearing elements. The bearing elements are mounted to and distributed circumferentially about an axis of the support ring. At least one of the bearing elements includes a polycrystalline diamond table, a substrate bonded to the polycrystalline diamond table, bonding region defined by the substrate and the polycrystalline diamond table, and a corrosion resistant region. The corrosion resistant region includes a corrosion resistant material that covers at least a portion of at least one lateral surface of the bonding region. The corrosion resistant region prevents corrosion of at least some material in the bonding region covered by the corrosion resistant region (e.g., during use). Other embodiments employ one or more sacrificial anodes as an alternative to or in combination with the corrosion resistant region.

Radial bearing

Embodiments of the invention relate to bearing apparatuses in which one bearing surface of the bearing apparatus includes diamond, while another bearing surface includes a non-diamond superhard material (e.g., silicon carbide). For example, a bearing apparatus may include a bearing stator assembly and a bearing rotor assembly. The bearing stator assembly and bearing rotor assembly each include a support ring and one or more superhard bearing elements generally opposed to one another. The bearing surface(s) of the rotor or stator may include diamond, while the bearing surface(s) of the other of the rotor or stator do not include diamond. Another bearing apparatus may include both thrust- and radial bearing components. The generally opposed thrust-bearing elements may include diamond, while the generally opposed radial bearing elements may not include diamond, but include a non-diamond superhard material, such as silicon carbide.
