A sliding bearing that operates under sliding friction. The sliding bearing works stably, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricating oil without direct contact, which can also greatly reduce the friction loss and surface wear, and the oil film also has a certain vibration absorption capacity. But the starting friction resistance is large. The part of the shaft supported by the bearing is called the journal, and the parts matching the journal are called bearing shells. The antifriction material layer cast on the inner surface of the bearing pad to improve the friction property of the bearing pad surface is called the bearing bushing
