SLIDING BEARING AND METHOD OF MANUFACTURING SAME

摘要

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.
