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.

Provided is a partially-cylindrical sliding member including a sliding layer including fibrous particles having an average particle size of 5-25 m dispersed in a synthetic resin at a volume ratio of 10-35% of the sliding layer. The particles having a major axis length 20 m are included at a volume ratio of 10% to total particles. A sliding surface side area is defined from the sliding surface and has a thickness of 25% of a sliding layer thickness T, where the fibrous particles having a major axis length of 20 m have a dispersion index of 1.1-6. An interface side area is defined from the interface and has a thickness of 25% of T, where the dispersion index is 1.1-6. An intermediate area is defined between the both areas, where the dispersion index is 0.1 to less than 1.

Plain bearing providing an outer ring with an inner surface, an inner ring with an outer surface, the rings being symmetrical around an axis and metallic, at least on the rings being a textured ring with a texturation consisting of a plurality of micro-cavities arranged onto a textured surface. A composite self-lubricating composite liner that is interposed between the inner surface of the outer ring and the outer surface of the inner ring, so that upon sliding movement of the textured ring with respect to the composite liner, some solid particles of the liner, acting as a solid lubricant, are detached from the composite liner and migrate between the sliding surfaces until they get retained into the micro-cavities.

The invention relates to an anti-friction lacquer having a polymer as a resin matrix and functional fillers, the functional fillers containing mixed-phase oxides and optionally further functional fillers. The invention further relates to a sliding element having a metallic substrate layer and a coating which is applied thereon and made of at least such an anti-friction lacquer and to a method for the production thereof.

A rolling bearing has an outer diameter surface of the outer ring which is a fitting surface with a housing and the inner diameter surface of the inner ring, which is a fitting surface with a shaft. The outer diameter surface of the outer ring or the inner diameter surface of the inner ring is coated with a bonded film containing an organic binder, a solid lubricant powder such as molybdenum disulfide powder, and a friction/wear modifier such as antimony oxide powder. According to the rolling bearing, a creep resistance is kept excellent without causing increase in cost and size and being deformed and softened.

A sliding-hearing composite material includes a steel supporting layer (10), an intermediate layer (12) based on an aluminum alloy that is free of lead, and a bearing metal layer (14) based on an aluminum alloy that is free of lead, wherein the aluminum alloy of the intermediate layer (12) has a composition having 3.5 to 4.5 wt % copper, 0.1 to 1.5 wt % manganese, 0.1 to 1.5 wt % magnesium, and the usual admissible impurities, the remainder being aluminum, and wherein the aluminum alloy of the bearing mental layer (14) has a composition having wt % tin, 1.0-3.0 wt % nickel, 0.5-1.0 wt % manganese, 0.5-1.0 wt % copper, 0.15-0.25 wt % chromium, 0.1-0.3 wt % vanadium, and the usual admissible impurities, the remainder being aluminum. A sliding bearing element and the use of the sliding-bearing composite material for sliding bearing element, particularly sliding bearing shells, sliding bearing bushes, or thrust washers is also disclosed.

A sliding bearing element has a steel supporting layer onto which a 2-layer composite is applied which consists of an aluminum-based substrate having a layer thickness hs of 0.2 to 0.4 mm and an aluminum-based sliding layer having a layer thickness hG of 0.005 to 0.1 mm. The substrate and the sliding layer are joined by roll bonding. A sliding bearing is made from two sliding bearing elements of this kind, which are predominately used for applications in high-performance engines, principally for connecting-rod bearings, crankshaft main bearings and connecting rod bushes, but also in applications in mounting camshafts and counterbalance shafts as well as transmissions.

A clamping bushing which, due to the particular eccentric geometry and composite materials used to manufacture the same, comprising elastomers (14, 15) and metal sheets (10, 11), is suitable for the reduction of principally vertically acting vibrations and structure-borne sound which can arise in machines/gearboxes and, in particular, in wind turbines.

A plain bearing, having a bearing base body made from a metallic material, having an intermediate layer made from a metallic material applied onto the bearing base body, and having a plain-bearing layer made from a non-metallic material applied onto the intermediate layer. The intermediate layer is an arrangement of wires or a perforated plate. The arrangement of wires or the perforated plate forms undercuts and the plain-bearing layer is a layer made from polyether ether ketone.

A rolling bearing has an outer diameter surface of the outer ring which is a fitting surface with a housing and the inner diameter surface of the inner ring, which is a fitting surface with a shaft. The outer diameter surface of the outer ring or the inner diameter surface of the inner ring is coated with a bonded film containing an organic binder, a solid lubricant powder such as molybdenum disulfide powder, and a friction/wear modifier such as antimony oxide powder. According to the rolling bearing, a creep resistance is kept excellent without causing increase in cost and size and being deformed and softened.
