A grease for a rolling bearing of an information recording and reproducing apparatus contains a base oil, a thickener, and at least one kind of an antioxidant selected from an amine-based antioxidant expressed by the General Formula (1), and a phenol-based antioxidant expressed by the General Formula (2). The base oil contains a refined mineral oil classified as Group III in a base oil category defined by the American Petroleum Institute, and the flash point of the refined mineral oil is 240 C. or higher.

Provided herein is a composition for treating aluminum containing surfaces, wherein the composition includes a reaction product of at least one amine-functionalized organosilane and/or oligomer and/or polymer thereof and at least one fatty acid, wherein the molar ratio of the amino group/s of the at least one amine-functionalized organosilane and/or oligomer and/or polymer thereof and of the at least one fatty acid is 1.2:1 to 1:2, and wherein the at least one amine-functionalized organosilane and/or oligomer and/or polymer thereof is linked to the at least one fatty acid by at least one carboxylic acid/amine salt bond and/or at least one amide bond.

A metalworking fluid includes a pH buffer system having one or more organic acids and one or more organic amines. The organic acids, which include aromatic carboxylic acids and C.sub.10 or higher aliphatic carboxylic acids, may replace boric acid, such that boric acid may be excluded from the metalworking fluid. The organic acids may include at least one of phthalic acid, isophthalic acid, and terephthalic acid. The one or more organic amines include aliphatic and aromatic amines having an amine value of at least 50 mg KOH/g. A method of using the metalworking fluid includes shaping a metal by contacting the metal surface with a tool while cooling and lubricating at least one of the metal surface or tool with the metalworking fluid.

The presently disclosed subject matter Is directed to formulations for lubricating a conveyor belt used in beverage packaging. One of the disclosed lubricant compositions comprises water, at least one amphoteric surfactant, at least one anionic surfactant and at least one non-ionic surfactant. Also disclosed is a system for applying a lubricant to a conveyor belt and a method for lubricating a conveyor belt.

An overbased calcium magnesium sulfonate grease composition and method of manufacture comprising both overbased calcium sulfonate and overbased magnesium sulfonate in a ratio range of 60:40 to 100:1. The grease is made according to any known method for making an overbased calcium sulfonate grease by using the overbased magnesium sulfonate in addition to the overbased calcium sulfonate. A portion of the magnesium sulfonate may be added prior to conversion and another portion after conversion, with or without one or more delay periods between the addition of water or other reactive ingredient and the addition of magnesium sulfonate. The grease can be made using calcium hydroxyapatite and/or added calcium carbonate as calcium containing bases for reacting with complexing acids, a non-aqueous converting agent delay method, added alkali metal hydroxide, or any combination thereof. The grease has a high dropping point and reduced thickener yield.
