A water-based lubricating grease composition includes at least 40 wt % water; a salt-based thickener; a polymer-based thickener; and optionally, an inorganic solid-based thickener. A process for preparing the water-based lubricating grease composition may include blending a suitable amount of water with a salt-based thickener to provide a thickened water-based grease, wherein the salt-based thickener is obtained from contacting a base with a fat; and adding a polymer-based thickener to the thickened water-based grease.

The rolling bearing of the present invention is lubricated with a lubricant composition which contains a fatty acid metal salt, a metal dithiocarbamate, a phosphorous-type additive, and a basic additive, and which has a total acid value of 3.7 mgKOH/g or more. The rolling bearing makes it possible to further improve anti-fretting performance, and to reduce a decrease in fretting resistance even when used under the circumstance that fluorine-type grease penetrates into the bearing using urea-type grease.

Lubricant composition, in particular a cooling lubricant solution, based on ionic and/or organoelemental compounds.

A fabrication fluid composition, such as a metal cutting fluid concentrate, contains water, a first surfactant which is an anionic surfactant, a second surfactant which is an amphoteric surfactant, a third surfactant which is selected from an anionic surfactant and an amphoteric surfactant, the third surfactant being different from the first and second surfactants, and water, along with at least one of an anti-rust agent, a coloring agent, and a de-foaming agent. The concentrate may be combined with water to provide a fabrication fluid such as a metal cutting fluid composition that may be applied to a piece of metal being cut for a time and in an amount effective to dissipate heat from the metal being cut.

Disclosed is a lubricant for use in cold forming of a metal. The lubricant comprises a mixture of at least one lubricating compound and at least one starch. The starch adheres the lubricating compound to the metal surface. The present lubricant completely removes the need to pre-coat the metal with a zinc phosphate coating to adhere the lubricating compound to the metal. The present lubricant eliminates several steps required in processes that utilize zinc phosphate pre-coatings. In addition, the lubricant of the present invention is easily removed after the cold forming operations unlike zinc phosphate coatings.

Emulsions including an additized oil phase and a water phase additive blend are disclosed. The components of the additized oil phase and the water phase additive blend do not interact. The emulsions are useful as metalworking fluids. Methods of making and using the emulsions are also disclosed.
