Abstract: A bearing material may include a polymeric matrix of polyamide-imide (PAI) polymer material and a plurality of melamine cyanurate particles dispersed within the polymeric matrix.

Abstract: A sliding element for an engine may include a polymer-based overlay layer and a metallic substrate. The polymer-based overlay layer may include a polymer-based matrix, a metal particulate, and a pigment. The pigment may have a hardness of at least 4 on the Mohs hardness scale.

Abstract: A sliding element for an engine may include a metallic substrate, a first polymer-based layer, and a second polymer-based layer. The first polymer-based layer may include a polymeric material and may be disposed on the metallic substrate. The second polymer-based layer may include a polymeric material and may be disposed on the first polymer-based layer. The polymeric material of the first polymer-based layer may be the same as the polymeric material of the second polymer-based layer. The second polymer-based layer may further include a tungsten disulphide particulate.

Abstract: A bearing material for a bearing element (e.g., a crankshaft bearing) and a method of making a bearing material are disclosed. The bearing material includes a polyamide-imide plastics polymer material functionalised with hydrocarbon groups. In one example, the method includes preparing a polyamide-imide polymer material and, when the polyamide-imide polymer material reaches a predetermined molecular weight, adding a hydrocarbon-containing reactant to a reaction mixture containing the polyamide-imide polymer material to form a bearing material comprising a polyamide-imide plastics polymer material functionalised with hydrocarbon groups. In another example, the method includes mixing a polyamide-imide plastics polymer with a catalyst to form a reaction mixture, and adding a hydrocarbon-containing reactant to the reaction mixture to form a bearing material comprising a polyamide-imide plastics polymer material functionalised with hydrocarbon groups.

Abstract: A bearing material may include a polyamide/imide plastics polymer material having an amine content including a fluorinated diamine and a non-fluorinated diamine.

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.
