introduction： one、Improper installation(Account for about16％) 1、Use brute force when installing，Hit the bearing directly with a hammer[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The greatest damage to bearings;It is the main cause of deformation。 2、Inadequate installation，Mounting is deviated or not installed to the bearing position，Cause the bearing clearance is too small。The inner and outer circles are not in harmony
