Single direction thrust ball bearing can only bear the load in one direction, if bear the load in two directions, you must use two-way thrust ball bearing. Thrust ball bearing must apply minimum load or preload. When the shaft is vertical, the weight of the shaft usually exceeds the minimum load. At this time due to the influence of the opposite direction of the axial external load, the role of the load is likely to reduce.
