Abstract: A sliding member of the present embodiment includes a bearing alloy layer and a coating layer provided on a sliding surface side thereof. The coating layer has a resin binder with sulfide particles dispersed therein. A covering portion is provided over specific particles and is made of metal oxide comprising the same metal element as a metal element constituting the sulfide particles. When measured by an X-ray photoelectron spectroscopy and an X-ray diffraction method, a ratio of a peak height of the metal oxide to a peak height of metal sulfide by the X-ray photoelectron spectroscopy is from 0.10 to 0.50, and a ratio of the peak height of the metal oxide to the peak height of the metal sulfide by the X-ray diffraction method is 0.10 or less.

Abstract: A bearing device includes a base plate, a plurality of sliding pads and support members. The sliding pad is movable relative to the base plate. The support members are located between the base plate and the sliding pad, and shift a position of a load supporting point in a circumferential direction of the base plate, the load supporting point serving as a point for supporting a load received from the sliding pad. When any virtual flat surface perpendicular to a rotating shaft member is considered as a reference surface, and when a distance from the reference surface through the load supporting point to an end of the sliding pad at the opposite side to the base plate is defined as a setting distance, a position of the load supporting point is shifted in a circumferential direction of the base plate with no change in the setting distance.

Abstract: Provided is a partially-annular sliding member including a sliding layer including fibrous particles having an average particle size of 5-25 μm dispersed in a synthetic resin at a volume ratio of 10-35% of the sliding layer. The particles having a major axis length≤20 μm are included at a volume ratio of ≥10% to total particles. A sliding surface side area is defined from the sliding surface and has a thickness of 25% of a sliding layer thickness T, where the fibrous particles having a major axis length of ≥20 μm have a dispersion index of 1.1-6. An interface side area is defined from the interface and has a thickness of 25% of T, where the dispersion index is 1.1-6. An intermediate area is defined between the both areas, where the dispersion index is 0.1 to less than 1.

Abstract: A connecting rod bearing for a crankpin of a crankshaft of an internal combustion engine includes a pair of half bearings forming a cylindrical shape. Each half bearing has a main cylindrical portion including a circumferentially central portion of the half bearing, and crush reliefs formed on both circumferential sides of the main cylindrical portion with a wall thickness being smaller than that of the main cylindrical portion. At least one half bearing has an axial groove which extends in an axial direction on a slide surface of the main cylindrical portion, and is apart from the circumferentially central portion by a circumferential angle of 10° or more toward a forward side in a rotation direction of the crankpin, and apart from the crush relief by a circumferential angle of 10° or more toward the circumferentially central portion.

Abstract: A half thrust bearing having a semi-annular shape includes a sliding surface for receiving an axial force of a crankshaft of an internal combustion engine, and a rear surface on an opposite side of the sliding surface, and defines a reference plane on the rear surface side that is perpendicular to an axial direction. The sliding surface includes a flat surface portion near a circumferentially central portion and in parallel with the reference plane, and inclined surface portions on both sides of the flat surface portion in a circumferential direction. At any radial positions of the half thrust bearing, an axial distance between the reference plane and the sliding surface is maximum at the flat surface portion, and is reduced in the inclined surface portions toward both circumferential end portions of the half thrust bearing.

Abstract: A half thrust bearing includes a sliding surface for receiving an axial force of a crankshaft of an engine, and a rear surface on an opposite side thereto. The sliding surface includes a flat surface portion near a circumferentially central portion, and two inclined flat surface portions on both circumferential sides of the flat surface portion. The axial distance between the rear surface and the sliding surface is maximum at the flat surface portion. At any radial positions, the axial distance in each inclined flat surface portion is maximum on a circumferentially central portion side and is reduced toward a circumferential end portion of the half thrust bearing. Each inclined flat surface portion is arranged to form one constant thickness portion extending linearly from a radially inner end to a radially outer end at a circumferential angle of 45°.

Abstract: Disclosed herein is a sliding member that has a coating layer serving as a sliding surface thereof so that even when foreign matter enters between the coating layer and a partner member, smoothness between them is maintained to prevent the occurrence of seizing. When the coating layer has an elastic recovery ratio of less than 60%, foreign matter that has entered between the coating layer and the sliding surface of a partner member is efficiently embedded in the coating layer. When the coating layer is formed of a resin composition, the resin composition contains a binder resin, a solid lubricant, and metal particles having a Young's modulus of 10 GPa or more but 100 GPa or less.
