Abstract:
A lubricant composition for lubricating an interface between an inner surface of a tire and a safety support ring in a run-flat tire system that includes a lubricating agent selected from glycerol, polyalkylene glycol or combinations thereof and a thixotropic agent. The thixotropic agent is an organoclay comprising a mineral clay mixture treated with an alkyl quaternary ammonium salt, wherein the mineral clay mixture comprises at least one of sepiolite, palygorsl¬te and a smectite and wherein a combined amount of palygorskite and sepiolite in the mineral clay mixture is between about 50 wt. % and about 100 wt. % with a balance of the mineral clay mixture being essentially the smectite. The lubricating agent may also be selected from a copolymer that is a mixture of alkylene oxides, preferably a mixture of ethylene oxide and propylene oxide.
Abstract:
A perfluoropolyether, a composition comprising the perfluoropolyether, a process for producing the perfluoropolyether, and a process for improving the thermostability of grease or lubricant are provided. The perfluoropolyether comprises (1) perfluoroalkyl radical end groups in which the radical has at least 3 carbon atoms per radical and is substantially free of perfluoromethyl and perfluoroethyl end groups or (2) at least one bromine or iodine atom at the primary position of the perfluoropolyether.

Abstract:
In a synthetic resin-made thrust sliding bearing 1, a silicone grease whose base oil is a silicone oil, whose coefficient of kinematic viscosity at 25°C is not less than 100 cSt and not more than 500,000 cSt, and which contains a thickener so as to set its worked penetration to not less than 200 and not more than 400 is interposed at sliding interfaces between, on the one hand, an upper surface of a lower annular flat plate-shaped portion 202 defining a bottom surface of a lower annular recess 204 and a lower surface of an upper annular flat plate-shaped portion 102 and, on the other hand, an upper surface and a lower surface of a thrust bearing piece 300 which are respectively brought into sliding contact with the upper and the lower surface.
Abstract:
A lubricating oil composition comprising base oil, glycerol monooleate and one or more nitrile compounds; and a method of lubricating an internal combustion engine comprising applying said lubricating oil composition thereto.
Abstract:
The invention relates to a lubricating composition which can be used to lubricate an interface between a tyre casing and a safety support which is mounted to the wheel rim inside said casing. The invention further relates to one such casing and a mounted assembly for a motor vehicle which are provided with the aforementioned lubricating composition. The inventive lubricating composition is characterised in that it comprises an alkene oxide polymer (polyoxyalkene) as a lubricating agent and between 4 % and 7.5 % silica (weight percent of the lubricating composition) as a thickening agent.
