    Abstract: In this sliding bearing, which is provided with a resin coating layer at the surface of a bearing alloy layer layered at a back metal layer, a PAI that degrades with difficulty at high temperatures is used as the main component as the resin binder of the resin coating layer, adjustment particles are included in the resin binder, and as a result, the compressive strength of the resin coating layer is increased, and indentations of the resin coating layer resulting from a shaft are prevented. Meanwhile, a plate solid lubricant is included in the resin binder, and thus sliding characteristics are improved. Also, delamination due to cracks is prevented by the effect of adjusting the orientation of the solid lubricant and the damming effect of the adjustment particles, and thus superior anti-seizure property is provided even in an engine that frequently repeats starting and stopping.

    Abstract: A connecting rod bearing in which a semi-cylindrical bearing has an inner circumferential groove that extends from an abutting end with respect to another semi-cylindrical bearing toward a circumferential center part of the semi-cylindrical bearing, and is in alignment with an outlet port of a lubricant oil passage, the abutting end being oriented toward the same direction as a direction of relative rotation of the crankpin with respect to the connecting rod bearing. The dimension are sized such that the connecting rod bearing is capable of preventing large size foreign substances from entering into the clearance defined along the inner surface of the connecting rod bearing even though foreign substances, accompanied in the lubricant oil which is fed to the connecting rod bearing from a cylinder block of an internal combustion engine through the journal portion of a crankshaft, is not caused to discharge from the connecting rod bearing.

    Abstract: A main bearing for a crankshaft of an internal combustion engine comprises a pair of semi-cylindrical bearings. An oil groove extends on an inner circumferential surface of one semi-cylindrical bearing in a circumferential direction so that the center thereof in an axial direction aligns with that of an inlet opening of a lubricating oil path in a journal section of the crankshaft. The oil groove does not extend up to an axial direction groove formed at a joint portion of the semi-cylindrical bearings so that a separation inner circumferential surface extends between a circumferential direction end portion of the oil groove and the axial direction groove. The length of the separation inner circumferential surface is smaller than that of the inlet opening in the circumferential direction.

    Abstract: A sliding resin composition is provided which rapidly forms a transfer adhesion film of PTFE on the surface of a counter member at the initial stage of sliding. That is, in the case of using resin composition 1 which is in such a state that particles of PTFE 3 having PTFE film forming agent 4 embedded are dispersed in synthetic resin 2, when the surface of particles of PTFE 3 on the sliding surface of resin composition 1 contacts with the surface of an associated shaft, the PTFE film forming agent 4 is also present at the contact portion, whereby transfer adhesion of PTFE 3 to the surface of the associated shaft is accelerated and thus the time required for decrease of coefficient of friction can be shortened.
