    摘要： A sintered metal bearing includes: a sintered-metal bearing body formed of a metal different from a metal of a shaft and including a large number of inner pores; and a resin film formed on predetermined parts of a surface of the sintered-metal bearing body and forming a sliding surface. The resin film is formed so that surface openings communicating to the inner pores are kept opened, and resin-film parts adhere to a surface of the shaft. Further, a shaft member used for a sliding bearing unit is incorporated in a sintered-metal sliding bearing including copper mainly or copper and iron, the shaft member including a sliding surface. The shaft member includes: a metal shaft body; and a resin film formed on predetermined parts of a surface of the metal shaft body and forming the sliding surface. The resin film is made of a resin excellent in adhering properties.

    摘要： A cage used in a ball bearing assembly is rendered to be of a ring shape having a plurality of pockets defined therein to hold a corresponding number of balls in a circumferential row. The radius of a bore of a circumferentially extending body of the cage as measured from the geometric center of the bore to an inner peripheral surface area of the circumferentially extending body aligned with each of the pockets is chosen to be greater than the radius as measured from the geometric center of the bore to a different inner peripheral surface area of the circumferentially extending body intermediate between the neighboring pockets.

    摘要： A cage for a ball bearing assembly has a pocket for accommodating one of the balls defined at a plurality of locations in a direction circumferentially thereof and each of the pockets has an inner surface so shaped as to represent a concaved spherical surface. A concaved portion extending from an open edge on the cage inner diametric side towards the cage outer diametric side is provided in an inner surface of each of the pockets. The sectional shape of the inner surface of this concaved portion in a cage circumferential direction is represented by an arcuate shape of a radius of curvature smaller than the radius of curvature of the concaved spherical surface defining the inner surface of the respective pocket. The inner surface of each of the pockets may be formed with a film.

    摘要： A cage (5) for a ball bearing assembly has a pocket (11) for accommodating one of balls defined at a plurality of locations in a direction circumferentially thereof and each of the pockets has an inner surface so shaped as to represent a concaved spherical surface. A concaved portion (13) extending from an open edge on the cage inner diametric side towards the cage outer diametric side is provided in an inner surface of each of the pockets (11). The sectional shape of the inner surface of this concaved portion (13) in a cage circumferential direction is represented by an arcuate shape of a radius of curvature (Rb) smaller than the radius of curvature (Ra) of the concaved spherical surface defining the inner surface of the respective pocket (11). The inner surface of each of the pockets (11) may be formed with a film.

    摘要： Impregnation of a resin into a sintered body (15) enables reduction in an amount of oil to be impregnated into inner pores. Further, by forming pores into which the resin is unimpregnated in a bearing surface (inner peripheral surface (15a)), it is possible to supply oil retained in the pores into bearing gaps and to cause the pores to function as filters for catching contaminants such as abrasion powder in a bearing.

    摘要： The raceway surfaces of the inner and outer rings 1 and 2 and the surfaces of the rolling elements 3 are formed with lubricating films 1a, 2a and 3a of polytetrafluoroethylene having average molecular weight of not more than 5000 {PTFE (A)}. PTFE heretofore used for rolling bearings is a polymer having average molecular weight of more than 1.times.10.sup.5 mostly 1.times.10.sup.6 -1.times.10.sup.7, but PTFE(A) is very low in shear strength and soft as compared with PTFE polymer.
