    Abstract: A main bearing for a crankshaft of an internal combustion engine is composed of a pair of semi-cylindrical bearings. An oil groove extending in a circumferential direction is formed on an inner circumferential surface of one semi-cylindrical bearing. The oil groove has the depth gradually decreasing toward a circumferential end surface of the one semi-cylindrical bearing, and defines a circumferential end portion on the circumferential surface without extending to an axial groove formed in a joint portion of the pair of semi-cylindrical bearings. An extension portion of the inner circumferential surface extends between the circumferential end portion and the axial groove, and a plurality of circumferential grooves extending in the circumferential direction is formed on the extension portion from the oil groove to the axial groove over an entire width of the circumferential end portion of the oil groove.

    Abstract: An object of the present invention is to provide a sliding member which can slide for a longer period of time even in a dry state. In the present invention, sliding layers 3 are provided on the surfaces of a base material 2, and the sliding layer 3 contains polybenzimidazole (PBI) and 1 to 70 vol % of a solid lubricant. Since PBI, which is a thermoplastic resin, has higher heat resistance and also has higher material strength than PAI, PI, and EP, which are the conventionally used thermosetting resins, the wear resistance and the anti-seizure property can be improved and a decrease in material strength caused by high-temperature atmosphere, heat generation at the time of sliding, etc. can be restrained. Furthermore, the initial conformability can be improved because of high elongation percentage. Also, since the sliding layer contains the solid lubricant, the coefficient of friction can be decreased, and hence the anti-seizure property can be enhanced.

    Abstract: The invention provides a method of processing an inner surface of a bearing having a cylindrical shape which bearing includes a resin layer composed mainly of a synthetic resin as the inner surface, the method improving roughness of the inner surface and dimensional accuracy of an inner diameter of the bearing without cutting the inner surface. According to the method, the bearing is press-fitted into a jig and then the jig is mounted on a chuck. Next, a mandrel having a cylindrical bar shape is inserted into an inner diameter portion of the bearing and then the mandrel is heated by a heater up to 250null C., for example. The mandrel is expanded due to thermal expansion by the heating so that the inner surface, i.e., a surface of the resin layer is pressed by a press face of a peripheral surface of the mandrel.
