    摘要: The present invention provides a grease composition capable of effectively preventing a rolling surface of a grease-enclosed bearing from having hydrogen brittleness-caused peeling and the grease-enclosed bearing. The grease composition includes a base grease consisting of a base oil and a thickener and an additive added to the base grease. The additive contains at least an epoxy compound. A mixing ratio of the epoxy compound to 100 parts by weight of the base grease is set to 0.05 to 10 parts by weight. The grease-enclosed bearing using the grease composition includes an inner ring (2) and an outer ring (3); a plurality of rolling elements (4) disposed between the inner ring (2) and the outer ring (3); and a sealing member (6) for covering openings (8a, 8b) disposed at both axial ends of the inner ring (2) and the outer ring (3). The grease composition (7) is enclosed on peripheries of the rolling elements (4).

    摘要: This invention relates to a water-soluble lubricant for warm or hot metal forming, comprising a high polymer compound which comprises an imide group, which has a weight-average molecular weight of from 1,000 to 1,000,000. The water-soluble lubricants of the invention possess exceptional lubricity for reducing friction between a die and a workpiece, have a minimal adverse effect on the operating environment, and can readily be treated in wastewater.
