Abstract: A sliding component may include an overlay comprising a polymeric material and a metal oxide. The metal oxide may have a thermal conductivity of greater than about 1.5 Wm?1K?1, and a Mohs hardness of between about 5 and about 7. The sliding component may be a sliding component for an engine, such as a bearing, a bearing shell, a bush, a thrust washer, a journal bearing or the like.

Abstract: A thrust washer for a sliding bearing may include a thrust washer substrate having an axial face. The thrust washer may also have a polymer layer of profiled thickness on the axial face of the substrate. The profiled polymer layer may be provided with at least one oil distribution groove.

Abstract: A thrust washer may include a metallic substrate layer having an axial substrate face. The thrust washer may also include a polymer layer on the axial substrate face. The polymer layer may have an axial polymer face opposed to the axial substrate face. The axial polymer face may be profiled and may have at least one oil distribution groove. At least one of the substrate layer and the polymer layer may be a machined layer having a thickness that may vary in correspondence with the at least one distribution groove.

Abstract: A flanged half-bearing includes at least one substantially semi-annular thrust washer with an internal periphery having lateral lugs and an intermediary stabilization lug projecting from the internal periphery of the thrust washer, and a semi-cylindrical half journal bearing shell having lateral recesses and an intermediary stabilization recess that are recessed into an axial end face of the bearing shell and are respectively connected to the lateral lugs and the stabilization lug of the thrust washer, wherein the stabilization lug has rotational stabilization edges that project substantially perpendicularly from the inner periphery of the thrust washer, and the stabilization recess is configured for axial relative movement of stabilization lug. An engine includes at least one such flanged half-bearing.

Abstract: A bearing arrangement comprising a bearing shell, and a bearing shell receiving element, wherein the bearing shell is cylindrical or part-cylindrical and has a circumferential oil supply slot, and the bearing shell receiving element has an oil supply channel located in correspondence with the oil supply slot.

Abstract: A crankshaft comprising a plurality of main journal bearing surfaces (102), a plurality of connector rod bearing surfaces (104), and at least one oil feed passageway (110) internal to the crankshaft, each of the at least one oil feed passageways (110) communicating with an inlet (122) and a plurality of outlets (124) located within bearing surfaces (102, 104), and wherein the inlet (122) is located within a first main journal bearing surface, and at least one of the outlets (124) is located within a further main journal bearing surface, and an engine and a vehicle comprising such a crankshaft.

Abstract: A bearing bush is described wherein the bush bore at the axial ends of the bush is provided with relieved portions extending at least a part of the distance around a circumference of the bush, the relieved portions being in the form of grooves in the bore surface.

Abstract: There is disclosed a split bearing comprising a semi-cylindrical bearing member having a concave bearing surface extending throughout the length thereof to a parting face at each opposed circumferential end of the bearing member. The bearing surface has formed thereon a sprayed bearing overlay extending over the whole bearing surface except for crush relief regions adjacent to the parting faces. The bearing member has a substantially constant outer diameter and inner diameter except at the crush relief regions, where the inner diameter is larger than at other regions of the bearing surface. There is also disclosed a method of making such a bearing. Less overlay material is required than in conventional split bearings.

Abstract: A plastics polymer-based bearing material and a method manufacture thereof are described, the material comprising a matrix of a polyimide/amide plastics polymer material and having distributed throughout the matrix: from 5 to less than 15 vol % of a metal powder; from 1 to 15 vol % of a fluoropolymer, the balance being the polyimide/amide resin apart from incidental impurities.
