  Some control measures to reduce bearing failure

  The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. It can be understood that it is used to fix the shaft so that it can only be rotated while controlling its axial and radial movement. If the shaft does not have a bearing, it will not work at all. So in the process of using bearings, how can we take effective...
