A hybrid bearing assembly includes a bushing. A sleeve is rotationally disposed within the bushing and a support layer is disposed around an outer perimeter of the bushing. A protective sleeve is disposed abutting the sleeve. A protective bushing is disposed abutting the bushing.

A drag link guide assembly for guiding a drag link comprises a slide bushing and a housing enclosing the slide bushing. The housing comprises a socket portion, into which the slide bushing is inserted. The slide bushing comprises a locating area for the drag link having a substantially circular cylindrical periphery with at least one plane torsional locking face. The slide bushing comprises an outward-pointing structure, which interacts with a mating structure that is provided on the internal surface of the housing. A method for producing a drag link guide assembly is furthermore described.

An apparatus is provided that includes a diamond bearing surface positioned in sliding engagement with an opposing bearing surface of a diamond reactive material. The opposing bearing surface is hardened via a material treatment.

Tooling for clocking dual eccentric bushings of a clevis so that the clevis and a lug can be pinned together, comprises a pin and a sleeve. The pin comprises a pin cylindrical portion, a plate-engagement portion, and a stop surface. The sleeve comprises a sleeve cylindrical outer surface and a sleeve interior channel that has an interior-channel central axis, which is parallel to and offset from a sleeve-cylindrical-outer-surface central axis. The pin cylindrical portion is configured to be received by the sleeve interior channel with a slip fit. The tooling further comprises a squaring plate that comprises a squaring-plate abutment surface, configured to contact the stop surface, and a squaring-plate opening configured to receive the plate-engagement portion of the pin with a slip fit.

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.

A bearing unit of a yawing system of a wind turbine having a tower and a nacelle connected by the yawing system. The bearing unit includes an adjuster element moveably secured to the bearing unit, a body element translatable relative to the adjuster element, a bearing element in contact with the body element, and a biasing means positioned between the body element and the adjuster element for applying a tension force to the bearing unit. The adjuster element adjusts the tension force applied to the bearing unit through translation of the body element, and respective surfaces of the adjuster element and the body element are visible during use.

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.sup.3/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.
