Abstract: Water-based lubricants for the lubrication of frictional partners in drive elements, as well as their use. In particular, a water-based lubricant that contains 5 to 80% by weight of water-soluble polyalkylene glycol that is selected from the group that is composed of statistically distributed polyoxyethylene units and/or polyoxypropylene units and/or other polyoxyalkylene components, a block polymer that that is composed of polyoxyethylene units and/or polyoxypropylene units and/or other polyoxyalkylene components, 0.5 to 20% by weight of foaming or non-foaming emulsifiers from the class of anionic, non-ionic, or cationic surfactants, water-soluble or water-emulsifiable carboxylic acid esters, 0.5 to 50% by weight of anti-icing additives, selected from the group that is composed of alkylene glycol, glycerol, salts or ionic liquids, 0.05 to 10% by weight of corrosion additives, 0.001 to 1% by weight of additives for preventing the formation of foam, and 0.

Abstract: A method in which an improved lubricating composition containing ionic liquids is used to enable operation of chains, steel belts, wheel bearings, roller bearings, sliding bearings and electric motors for at least 48 hours by reducing the evaporation loss and the lackification tendency of the lubricant due to the lubricant being protected against thermal and oxidative attack.

Abstract: The invention relates to the use of ionic liquids for production of water-resistant lubricating grease compositions, which are used in a temperature range from at least 30° C. to at least 180° C. and have good anticorrosion properties.

Abstract: The invention relates to a lubricant composition based on modified, natural and renewable raw materials, the viscosity of which can be adjusted according to the application. The invention relates more particularly to biodegradable lubricant compositions.

Abstract: The invention relates to lubricating grease compositions having a base oil mixture based on oils having viscosities (ISO VG 2 to ISO VG 1500) that are standard for industrial lubricants, an ionic liquid, a thickening agent, e.g., based on a polyurea compound and conventional additives that can be used at current service temperatures that are higher than 120° C. to 260° C., in particular at a service temperature in the region of high service temperatures that are higher than 180° C. to 260° C. and also at low temperatures as low as ?60° C. The invention also relates to a method for producing said type of lubricating grease compositions.

Abstract: A lubricating grease composition that is a mixture of (a) a hydrocarbon-based oil, (b) a perfluoro-polyalkyl ether oil of the formula A′—(O—CF2)v—(O—C2F4)w—(O—C3F6)x—(O—C4F8)y—(O—CF2CF(CF3))z—O—A″  in which A′ is —CF3, —C2F5, —C3F7, or —CF2T where T is H or Cl, A″ is A′ or —CF3, C2F5, —C3F7, or —CF2T, where T is H or Cl1 and v, w, x, y and z are whole numbers ≧0, (c) a dicarbamide as a thickening agent, (d) typical additives and (e) organic and inorganic solid lubricants. A process for the production of the lubricating grease composition is also provided.

Abstract: A lubricant grease composition comprising is disclosed. The composition includes:(a) an oil or oil mixture of one or more ester of aromatic tricarboxylic or tetracarboxylic acids with an alcohol or a mixture of alcohols having the general composition C.sub.n H.sub.2n+1 OH with n=7 to 22 and/or one or more of the esters of trimethylolpropane, pentaerythritol or dipentaerythritol with aliphatic carboxylic acids having the general composition C.sub.n H.sub.2n+1 COOH with n=6 to 21,(b) a thickening agent comprising a biurea and/or polyurea, and(c) a wear-protecting additive comprising a mixture of the components triaryl phosphorothionate, C.sub.8 -C.sub.20 alkylamino monohexyl and dihexyl phosphate and C.sub.1 -C.sub.8 -alkylamino isobutyl phospate.

Abstract: A seal arrangement for the gap between a surface of an element rotating around its axis which is to be sealed, and a seal carrier at a distance from it. The seal arrangement includes a sealing ring of a polymeric material, which is at least partially surrounded by the seal carrier in the region of a holder segment and is connected with it so as not to rotate. The sealing ring touches the surface with a lip segment pressed on it in an elastic manner; the sealing ring has at least one ring segment which is expandable by means of a medium to which pressure can be applied, and is pressed against the surface. The ring segment of the sealing ring is arranged at least partially outside of the region of the holder segment surrounded by the seal carrier.
