    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.

    摘要： The present invention provides a grease composition which contains a small amount (not more than 0.06 wt %) of molybdenum and yet is capable of achieving an excellent low friction property when mechanical parts in which the grease composition has been packed are operated under a severe sliding condition in which they are subjected to a high speed and a high contact pressure. The present invention also provides a bearing, a universal joint, and a linear motion device in which the grease composition of the present invention is packed. A grease composition (7) is packed inside a grease-packed bearing (1) in such a way that the grease composition (7) is applied to at least the circumference of each rolling element (4). The grease composition (7) contains base oil, a thickener, and an additive. The additive includes molybdenum dithiocarbamate and sodium dithiocarbamate. The content of the molybdenum for the whole weight of the grease composition (7) is set to not more than 0.06 wt %.
