  Working Principle :

Thrust ball bearing is a kind of separable bearings, shaft ring component separation, the seat ring can and cage, ball. The shaft is matched with the shaft of the ring, ring is matched with the bearing seat hole ring, a gap between the shaft and the; thrust ball bearings can only bear the axial load, one-way thrust ball bearings can withstand axial load is a direction of the axial load, two-way thrust ball bearings can withstand the two directions of the thrust; ball bearing can limit shaft radial displacement, limit rotational speed is low, the axial displacement in one direction one-way thrust ball bearing can limit shaft or shell, two-way bearing can limit the axial displacement in two directions.
