    摘要： A rolling bearing in which the attainment of excellent current-carrying capability is compatible with cost reduction. The rolling bearing comprises an inner ring, an outer ring, and a plurality of rolling elements arranged between the inner and outer rings, oil films being interposed between the rolling elements and raceway surfaces of the-rings. Here, the inner raceway surface and the outer raceway surface are made coarser to such a surface roughness (Ra=0.1 &mgr;m or so) that they come into metal contact wit the rolling elements for electric connection.

    摘要： A fluid dynamic bearing device including: a bearing sleeve fixed to an inner periphery of a housing; a shaft member removably inserted along an inner periphery of the bearing sleeve; an annular member having an inner peripheral surface for defining a radial gap together with an outer peripheral surface of the shaft member; and radial bearing portions and a thrust bearing portion for supporting the shaft member. At least the radial bearing gap at each of the radial bearing portions, and a bottom gap having the thrust bearing portion received therein are filled with lubricating oil. A void section is formed in an interior space of the housing. Assuming that d1 represents a gap width of the radial bearing gap and d2 represents a gap width of the radial gap, a relationship of 30d1≦d2≦250d1 is satisfied.

    摘要： A fluid dynamic bearing device includes: a shaft member; a bearing sleeve which forms a radial bearing gap between the bearing sleeve and an outer peripheral surface of the shaft member; a housing which accommodates the bearing sleeve and is opened at both ends; and a lid member which closes an opening on one end side of the housing and forms thrust bearing portions. The housing is an injection-molded product into which the bearing sleeve is inserted, and the housing has another end with which a seal portion forming a seal space is integrally formed. The lid member is fitted with the outer peripheral surface of the housing by loose fitting so that the lid member and the housing are bonded and fixed to each other.

    摘要： A hub (10) is a product formed by injection molding of a resin together with a core metal (13) as an inserted component, and the core metal (13) is exposed on a surface of the hub (10). With this configuration, a cavity of a die for molding the hub (10) is not divided by the core metal (13), and hence it is possible to suppress deterioration in fluidity of a resin due to arrangement of the core metal (13) in the cavity.
