摘要:
The invention provides a lubricant composition comprising an oil of lubricating viscosity and a protic acid salt of an N-hydrocarbyl-substituted gamma- (γ-) or delta- amino(thio)ester. The invention further relates to a method of lubricating a mechanical device with the lubricant composition.
摘要:
A sofa bed sliding system (100, 200, 300, 400, 500, 600, 700) for a sofa bed (1,1′) is provided. The sliding system is forming a connection between a moveable sofa bed part (3, 3′) and an associated frame structure (10, 10′), wherein said sliding system (100, 200, 300, 400, 500, 600, 700) comprises at least one sliding surface (110, 210, 310, 410, 510, 610) being coated with a lacquer comprising a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction.

The use of borated dispersant, preferably in combination with polyalkylenyl succinic anhydrides, to stabilise an additive concentrate which includes a salicylate detergent and a nitrogen-free ashless organic friction modifier.
摘要:
A lubricating composition for use in the crankcase of an engine comprising (i) a base oil; (ii) one or more organo-molybdenum compounds at a level sufficient to provide from 100 to 1000 ppmw of molybdenum; and (iii) from 0.2 wt % to 5.0 wt %, by weight of the lubricating composition, of one or more organic polymeric friction reducing additives, wherein the one or more organic polymeric friction reducing additives has a molecular weight ranging from 1000 to 30000 Daltons and is the reaction product of: a) a hydrophobic polymeric sub unit which comprises a hydrophobic polymer selected from polyolefins, polyacrylics and polystyrenyls; b) a hydrophilic polymeric sub unit which comprises a hydrophilic polymer selected from polyethers, polyesters, polyamides; c) optionally at least one backbone moiety capable of linking together polymeric sub units; and d) optionally a chain terminating group. The lubricating composition provides improvements in terms of reduced friction and wear, in addition to improved fuel economy performance.
摘要:
A lubricating oil composition contains a base oil, (A) a phosphate, (B) a thiophosphate and (C) a naphthylamine derivative. The lubricating oil composition is excellent in wear resistance and is unlikely to generate sludge even at a high temperature, and thus is suitable for an oil-impregnated bearing of a high-speed spindle motor provided to DVD-RAM, Blu-ray disc or the like.

摘要:
Lubricant compositions suitable for use in automotive engines, especially internal combustion engines, the lubricant having a kinematic viscosity at 100° C. of less than 12.5 mm2/s and a high temperature, high shear dynamic viscosity (i.e. at a temperature of 150° C. and a shear rate of 106/s) of at least 2.9 mPa.s, and comprising (a) 70 to 99.5 wt. % of a base oil, preferably a mixture of poly-alpha-olefin and ester, having a kinematic viscosity at 100° C. of 2 to 8 mm2/s and a viscosity index of at least 120, and (b) 0.5 to 3 wt. % of an alkenylarene-conjugated diene copolymer, preferably styrene/butadiene copolymer, as a viscosity index improver. The lubricant provides an improvement in fuel economy performance whilst maintaining effective lubrication of the engine under operating conditions.
