Abstract
A split-type sliding bearing for a crankshaft in an internal combustion engine fits within a bearing housing having a housing half with a higher thermal expansion coefficient, and a housing half with a lower thermal expansion coefficient. The pair of semi-cylindrical bearings includes first and second semi-cylindrical bearings, the first being supported on the housing half having a higher thermal expansion coefficient, and the second being supported on the housing half having a lower thermal expansion coefficient. The first and second semi-cylindrical bearings have equal outer diameter, and the first has circumferential ends having a thickness smaller than that of the opposite circumferential ends of the second semi-cylindrical bearing.
