    Abstract: The invention relates to a method of lubricating the bearings of solid fuel pulverizers, for example, coal pulverizers. The method involves supplying to the bearings a lubricating composition designed to have superior performance compared to conventional coal pulverizer bearing lubricants. The invention also provides a bearing lubricant for a coal pulverizer as well as its use in coal pulverizing equipment to improve the service life and/or durability of bearings in coal pulverizing equipment. The invention also provides an additive composition for use in a bearing lubricant for a coal pulverizer, as well as the use of the additive composition to improve the service life and/or performance of the bearing lubricant.

    Abstract: A liquid extreme pressure agent for use in lubricating compositions where the lubricating compositions comprise an oil of lubricating viscosity and the reaction product of: (a) a thiazole; (b) a composition comprising a carboxylic acid, a phosphorus containing acid or salt, or combinations thereof; and (c) an amine containing one or more branched hydrocarbyl groups. The invention also provides an additive composition comprising the reaction product described above and a process for making lubricating compositions, including greases, from the reaction product.
