ABSTRACT:
A sliding bearing comprises a back metal and a bearing alloy layer formed thereon, the thickness of the back metal gradually decreasing from the middle portion toward each axial end portion, and the thickness of the bearing alloy layer being increased at each axial end portion. The bearing alloy layer has a Young's modulus smaller than that of the back metal of steel plate and hence it is elastically deformed with greater ease, and therefore, particularly at the beginning of the use, the oil film pressure at each axial end portion becomes higher when misalignment takes place, with the result that the bearing alloy layer is elastically deformed in the direction of compression. In consequence, the oil film thickness at opposite end portions is increased to prevent rupture of oil film, thus avoiding occurrence of metal contact.
