PURPOSE:To manufacture a sliding bearing which can prevent seizure and wearresistance by forming a recess which is continuous circumferentially of an adapter and which has its inner surface with a widthwise sectional shape such as to have a flat center part and rise-up opposite end parts. CONSTITUTION:The inner surface of an adapter 2 has rise-up parts 2-1, 2-1 at opposite ends thereof in the widthwise direction of a bearing, and a flat part 2-2 in the inside inner surface thereof. Such a sectional shape structure is formed continuously in the circumferential direction. When an adapter 2 is attached thereto with a bearing metal 3, the rear surface of the bearing metal 3 is therefore made into close contact with the flat part 2-2 while both ends are bent inward. In this condition, the slide surface of the bearing metal 3 is machined by a broach cutter 1 in order to remove its margin. After the machining, the bearing is fitted in a flat adapter 2', there can be provided a bearing metal 3 having chamfered surfaces 3-1 at opposite ends of the bearing slide surface thereof, and a flat part 3-2 in the inside thereof. With this arrangement, it is possible to prevent seizure and abrasion due to eccentric contact. |
