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.
