Abstract

See full text

Disclosed is a sliding bearing consisting of a pair of semi-cylindrical bearings for supporting a crankshaft or a crank pin in an internal combustion engine. The sliding bearing is incorporated in a split-type bearing housing. One of the semi-cylindrical bearings being incorporated in at least one of the pair of housing halves, which one housing half has a relatively higher stiffness, is provided with a number of circumferential grooves on an inner surface of the semi-cylindrical bearing so as to extend circumferentially along the inner surface of the semi-cylindrical bearing. The circumferential grooves existing at least one circumferential end region of the inner surface of the semi-cylindrical bearing have a depth of not less than 10 μm, the circumferential end region including a circumferential bearing end face orientating a direction opposite to the rotation direction of the shaft or pin.
