  • Sliding bearing and method of manufacturing the same
    Patent number: 8545102
    Abstract: A cylindrical sliding bearing 1 can rotatably support a rotational shaft by a sliding surface 4 (inner circumferential surface). A crowning 5 having a sloped surface is formed at both ends of the sliding surface 4 in the axial direction. The crowning 5 includes a first crowning 3A formed of a sloped surface of a lining layer 3 and a second crowning 2A formed of a sloped surface of a back metal 2 positioned on the lower side of the first crowning. Unlike a conventional sliding bearing, the back metal 2 where the crowning 5 is positioned is provided as a sloped surface (2A). As compared with conventional bearings, the crowning 5 can be prevented from being unevenly brought into contact with the rotational shaft.
