滑動軸承，在滑動摩擦下工作的軸承?；瑒虞S承工作平穩、可靠、無噪聲。在液體潤滑條件下，滑動表面被潤滑油分開而不發生直接接觸，還可以大大減小摩擦損失和表面磨損，油膜還具有一定的吸振能力。但起動摩擦阻力較大。軸被軸承支承的部分稱為軸頸，與軸頸相配的零件稱為軸瓦。一般用過比較小的機械設備中，轉速較高的地方， 如電機，齒輪箱等等，滑動軸承應用場合一般在低速重載工況條件下，或者是維護保養及加注潤滑油困難的運轉部位， 如船舶的推進軸等。     

       Sliding bearing is used to work under sliding friction. The sliding bearing is stable, reliable and noise free. Under the condition of liquid lubrication, the sliding surface is separated by the lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced, and the oil film also has a certain absorption capacity. But the starting friction resistance is larger. The part supported by the shaft is called the journal, and the part matching the journal is called the bearing bush. Generally used in relatively small mechanical equipment, high speed, such as motor, gear box and so on, the application of sliding bearings in low speed heavy load conditions, or maintenance and injection of lubricating oil difficult operation parts, such as the propulsion shaft of the ship.
