Sliding bearing A bearing that works under sliding friction. Slide bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, friction loss and surface wear can be greatly reduced, and the oil film also has a certain ability of absorbing vibration. However, the starting frictional resistance is large. The part where the shaft is supported by the bearing is called a journal, and the part that matches the journal is called a bearing. The friction-reducing material layer cast on its inner surface to improve the frictional properties of the pad surface is called a bearing lining. Bearing pad and bearing material are collectively referred to as the plain bearing material. Sliding bearing applications are generally under low-speed, heavy-duty conditions, or are difficult to maintain and refill lubrication.
