    Abstract: A semi-cylindrical half bearing for a sliding bearing includes at least one axial groove formed on its inner circumferential surface that includes a smooth groove surface formed back away from the inner circumferential surface toward a radially outer side of the half bearing. The groove surface forms a convex curve toward the radially outer side in a cross-section perpendicular to the axial direction of the half bearing, and forms a straight line extending in the axial direction in a cross-section parallel to the axial direction. The half bearing further includes a plurality of axial narrow grooves formed on the groove surface so as to be back away from the groove surface toward the radially outer side, that extend in the axial direction of the half bearing.

    Abstract: A half thrust bearing includes a back metal layer, a bearing alloy layer defining a slide surface, and two thrust relieves formed adjacent to both circumferential end surfaces of the half thrust bearing and each including a thrust relief surface. The back metal layer includes an exposed end face configuring at least a part of the circumferential end surface, an exposed slant surface configuring at least a part of the thrust relief surface, and a transition surface formed between the exposed end face and the exposed slant surface. The transition surface is covered with a cover member including a cover end surface configuring at least a part of the circumferential end surface and a cover slant surface configuring at least a part of the thrust relief surface.

    Abstract: A bearing member according to an embodiment of the present invention is formed into a single cylindrical shape or a cylindrical shape divided into arcs along a circumferential direction, and is assembled to a housing on an outer peripheral side of the bearing member. The bearing member includes an outer peripheral surface provided on a side opposed to an inner peripheral surface of the housing. A maximum height Rz (μm) of a surface roughness of the outer peripheral surface is set as 2.00 μm≤Rz≤4.00 μm, and a value of ratio between an average protruding-peak height Rpk (μm) and a load length rate Mr1 (%), that is a load curve parameter for the surface roughness is set as 0.010≤Rpk/Mr1≤0.100.

    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: Provided is a semi-cylindrical-shaped half bearing having an inner surface including a center zone and end zones each including a plurality of recesses. Each recess includes a groove forming zone adjacent to the peripheral edge and including a plurality of circumferential grooves extending from the peripheral edge along the circumferential direction. An area ratio S2 of an area of the groove forming zone to an area of the recess in the end zone is larger than an area ratio S1 in the center zone. A maximum depth D4 of the circumferential groove in the end zone is larger than a maximum depth D2 of the circumferential groove in the center zone. A sliding bearing of the present invention includes the above half bearing.

    Abstract: Provided is a sliding member including: a back-metal layer and a sliding layer including a copper alloy. The back-metal layer includes a hypoeutectoid steel including 0.07 to 0.35 mass % of carbon and has a structure including a ferrite phase and pearlite. The back-metal layer has a high ferrite phase portion at a bonding surface between the back-metal layer and the sliding layer. A volume ratio Pc and a volume ratio Ps satisfy Ps/Pc≤0.4, where the volume ratio Pc is a volume ratio of pearlite in the structure at a center portion in a thickness direction of the back-metal layer, and the volume ratio Ps is a volume ratio of pearlite in the high ferrite phase portion.

    Abstract: Provided is a partially-cylindrical 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.
