                軸瓦

                Engine bearing
                 
                軸瓦屬於最簡單的一類軸承,僅有軸承面而無滾動元◇件。依賴油膜支撐機械元件〖做相對運動。在發動機內主要分為曲軸瓦和連桿瓦。
                Engine bearing (2 pcs Slide bearing) is the simplest type of bearing,comprising just a bearing surface and no rolling elements. It rides on a thin oil film supporting a mechanical element and providing its movement relatively .There are Main Bearing and Connecting rod bearing used in engines.
