    Abstract: Disclosed is a multi-layered plain bearing which comprises a steel back, an intermediate layer made of an aluminum alloy and an aluminum-base bearing alloy layer comprising one or more elements selected from the group consisting of Cu, Zn, Mg and Si. The aluminum-base bearing alloy layer is bonded to the steel back via the intermediate layer and subsequently subjected to a solid solution treatment at a temperature of not lower than 400null C. The adjacent region of the intermediate layer to the steel back consists of, by mass, 2% to 8% of Si, and the balance of Al and incidental impurities.

    Abstract: A bearing device includes a piston arranged in a cylinder of a rotor, and a half bearing mounted on the piston to support a roller. The piston includes a recessed holding surface, and holding side surfaces on both axial sides thereof. Each holding side surface includes a ridge portion having an arc-shaped or elliptic-arc-shaped profile protruding toward a radially inner side of the piston. The half bearing includes a partially cylindrical portion, and protruding portions at a circumferential center thereof. Each protruding portion has a protruding portion end face which includes a central recessed surface, and two support recessed surfaces located on both circumferential sides thereof, that have an arc shape or an elliptic arc shape to correspond to the profile of the ridge portion, so that only the two support recessed surfaces are in contact with the ridge portion.

    Abstract: Provided is a half bearing constituting a sliding bearing for a shaft member of an internal combustion engine that is unlikely to cause seizure in a sliding surface even if deflection or whirling of the shaft member occurs during an operation of the internal combustion engine. In a half bearing that constitutes a sliding bearing, a plurality of circumferential-direction grooves are formed to be adjacent to each other in a sliding surface, the sliding surface includes a plane portion that is parallel to an axial line direction and an inclined surface portion that is adjacent to the plane portion, the inclined surface portion is displaced from the plane portion toward an end portion of the sliding surface in the axial line direction such that the sliding surface successively comes close to a back surface, positions of maximum groove depths of the circumferential-direction grooves are located on groove center lines, the groove center lines in the inclined surface portion of the sliding surface are inclined relative to a vertical line toward the end portion of the sliding surface in the axial line direction, a groove inclination angle of the circumferential-direction groove that is the closest to the plane portion is a minimum angle, and the groove inclination angle successively increases toward the end portion of the sliding surface in the axial line direction.

    Abstract: Provided is a slide member having an overlay on a bearing alloy. The overlay has a thickness T and has a sliding surface and an interface with respect to the bearing alloy. The overlay includes an intermetallic compound and a matrix of Bi or a Bi alloy. In a thickness domain constituting 70%-75% of the thickness T of the overlay from the sliding surface to the interface, the volume proportion of the intermetallic compound is 10%-70%.

    Abstract: A half thrust bearing for a crankshaft of an internal combustion engine is formed of a back metal layer and a bearing alloy layer to have a slide surface and two thrust reliefs. Each thrust relieve includes a first region, where the back metal layer is exposed, on a circumferential end surface side, and a second region, where the bearing alloy layer is exposed, on the slide surface side while the slide surface includes two third regions adjacent to the second region, and a fourth region between the two third regions. A circumferential end region consists of the first, second and third regions. In the second region and the third regions, the bearing alloy layer includes a uniform thickness portion at a radial center, and a decreased thickness portion adjacent to an inner-diameter-side end surface.
