The main shaft and the rolling bearing are placed in a cast iron housing, which is centrally installed in the lower half housing of the fan and bolted.
A roller bearing is installed at each end of the spindle to bear the radial force. In order to bear the axial force, a centripetal thrust ball bearing is installed at the end of the near coupling to bear the axial force in the direction of the reverse airflow. The fan is equipped with a centripetal thrust ball bearing, and the primary fan is equipped with two centripetal thrust ball bearings.
