    Abstract: The subject of the invention is a method for increasing the strength properties of bearing sleeves and a unit for increasing the strength properties of bearing sleeves, to be used in manufacturing and regeneration of slide bearings with special working conditions, such as plane engines or rocket engines. Characterised by placing on the internal layer of the sleeve (T) a nanocomposite, graphene-like grease is placed, advantageously based on molybdenum disulfide, dissolved in anti-corrosion fluid, advantageously FC 111, in an amount of 2% to 10%, advantageously 5%, under the pressure within the range of 20 to 40 Mpa, advantageously 30 Mpa. This method is implemented in a unit characterized in that a cylindrical body, placed on a foundation (1) a sliding piston (2) is placed, having a central channel (3), connecting an impregnating chamber (4) with an impregnating socket (5), constructed in the pressing punch (6), in which a bearing sleeve (7) is placed, which has a hermetic connection of frontal surfaces with the operating surfaces of the punch (6) and upper surface of the piston (2), whereas in the external zone of the sleeve (T) the socket (5) has draining channels (8).

    Abstract: The invention provides a grease composition which is capable of extending the bearing life even at elevated temperatures and has little effect on acrylic rubber; and a bearing in which the above-mentioned grease composition is packed. The grease composition contains a thickener and a base oil, the base oil including a synthetic hydrocarbon oil in an amount of 20 mass% or more of the total mass of the base oil and an ester-based oil in an amount of 20 mass% or less of the total mass of the base oil, and the thickener containing a diurea compound represented by formula (I): R 1 -NHCONH-R 2 -NHCONH-R 3 wherein R 2 is a divalent aromatic hydrocarbon group having 6 to 15 carbon atoms, and R 1 and R 3 may be the same or different and represent cyclohexyl group or a straight-chain or branched alkyl group having 8 to 18 carbon atoms, with the ratio of the number of moles of the cyclohexyl group to the total number of moles of R 1 and R 3 being 60 to 95%. The bearing has the above-mentioned grease composition sealed therein.
