Abstract
A split-type sliding bearing for a crankshaft is formed of a pair of semi-cylindrical bearings halves which are fitted between a pair of housing halves having respectively high and low thermal expansion coefficients, one of the pair of bearing halves being supported on the housing half having a low thermal expansion coefficient, and the other of the pair of bearing halves being supported on the housing half having a high thermal expansion coefficient. The circumferential end zones of the bearing half supported on the housing half having a high thermal expansion coefficient have a thickness which is greater than that of the circumferential end zones of the bearing half supported on the housing half having a low thermal expansion coefficient.
