introduction：NTNAfter bearing installation，To check that the installation is correct，An operational check is required。Small machines can be turned by hand，To make sure the rotation is smooth。Check items for foreign bodies、scar、Poor operation due to indentation，Due to poor installation，The torque caused by poor machining of the mounting seat is unstable，Because the clearance is too small、Installation error、Seal friction caused by excessive torque and so on。Power operation can begin if there is no anomaly。Large machinery cannot be rotated manually，So cut off the power immediately after the no-load start，Mechanical idling，Check for vibration、noise、Whether the rotating parts are in contact, etc，After confirming that there are no anomalies，Entry motion
