摘要： A lubrication boosting additive comprising a mixture of a fluororesin, which is an alternating copolymer of a fluoroolefin and vinyl ether, soluble in an organic solvent and a phthalic ester in an organic solvent. The amounts of the organic solvent and the phthalic acid are, respectively, from 50 to 500 parts by weight and from 1 to 50 parts by weight per 100 parts by weight of the fluororesin. The additive is added to lubricating oils in an amount of from 0.1 to 10 g, calculated as the fluororesin, per liter of the lubricating oil.

摘要： The present invention provides a grease composition capable of securely preventing generation of a low-temperature abnormal noise when it is cold and a grease-enclosed bearing. A grease composition comprises a base oil and a thickener, wherein the base oil has a pour point not more than −50° C. and a kinematic viscosity not less than 15 mm2/s at 40° C. The base oil is at least one oil selected from a PAO oil and a perfluoro ether oil. The thickener is at least one substance selected from a urea compound and a fluororesin. A mixing consistency of the grease composition is in the range of 250 to 350. A grease-enclosed bearing has an inner ring, an outer ring, rolling elements interposed between the inner ring and the outer ring, and a grease composition enclosed on a periphery of the rolling elements. The grease-enclosed bearing is used for an automotive electric auxiliary machine.
