滚动轴承是各种动力传动机械中最易损坏的零件。其常见的损坏形式有：锈蚀、磨料磨损、压痕、疲劳磨损、抓粘磨损、保持架断裂、滚动体破碎、电流腐蚀等多种形式。造成轴承损坏的因素很多，如设计造型不正确、负荷过大、润滑不良等因素。这是仅谈一谈滚动轴承的正确选用及预防 Rolling bearings are the most easily damaged parts of various power transmission machinery. Common forms of damage are: rust, abrasive wear, indentation, fatigue wear, scratching stick wear, cage fracture, broken rolling, current corrosion and other forms. The bearing damage caused by many factors, such as design modeling is not correct, the load is too large, poor lubrication and other factors. This is just to talk about the correct selection and prevention of rolling bearings
