Thrust ball bearing is a kind of separation type bearings, shaft circle, seat ring may and maintain shelf, steel ball component separated. Shaft with circle is Axis collar, seat combined with circle is combined bearing hole between the collar, and axis; a gap. Thrust ball bearings can only carry axial load, i.e.one-way thrust ball bearings can only carry a direction is axial load, double To thrust ball bearings can withstand the two directions of the axial load; Thrust ball bearings can limit the radial displacement, the x axis Speed is low, i.e.one-way thrust ball bearings can restrict axis and the shell of a direction axial displacement, two-way bearing can limit Making the axial displacement of two directions. Double direction thrust ball bearings: have two cages with balls between the central shaft washer and two houding washers with flat seating surfaces. The shaft washer has raceways on both sides and is fixed on the journal. Bearings are able to carry only axial forces in both directions. Double direction thrust ball bearings can accommodate axial loads acting in both directions and can thus serve to axially locate a shaft in both directions. They must not be subjected to radial load.
