The present invention generally relates, in certain aspects, to corrosion inhibiting compositions useful for metalworking fluids, as well as concentrates, additives and metalworking fluids containing such compositions. The invention furthermore relates, in some aspects, to the use of such compositions for providing to a metalworking fluid one or more of anticorrosion performance, antifoam performance, antiwear performance, load carrying capacity, long fluid life, biological stability, lubricity, hard water tolerance, formulation stability.

A bearing includes a first member having a passageway configured to engage a shaft, the first member having a metallic material; and a second member disposed around at least a portion of the first member, the second member having a metallic material and at least one radially and inwardly bent portion capable of restricting axial movement of the first member. The first and second members are movable relative to each other.

According to the present invention, the composition for treating aluminum containing surfaces comprises the 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.

The invention provides a water-soluble metal-working oil agent, including a component A and a component B, wherein the component A is a mineral oil which has a characteristic temperature, as measured in accordance with JIS K2242, of 570 C. or higher, and the component B is at least one condensed fatty acid which is selected from a condensed fatty acid (1), produced through dehydration condensation of a hydroxycarboxylic acid, and a condensed fatty acid (2), produced through dehydration condensation of an alcoholic hydroxyl group of the condensed fatty acid (1) with a monovalent carboxylic acid, which has a characteristic temperature, as measured in accordance with JIS K2242, of 650 C. or higher. The agent can provide excellent workability with a hard-to-work material and can prolong tool life.
