Thrust ball bearing is made up of housing ring, axis ring and steel ball maintains module.Which is match for axis is called axis ring, which is match for shell is called housing ring.

According to the condition of accepting force, there ate one-way thrust ball bearing and double-way thrust ball bearing I.e.one-way thrust ball bearing and can withstand one-way axial load, two-way thrust ball bearings, it can be subject to bi-directional load. Among two-way thrust ball bearings, including ring and shaft to cooperate.The roller of these bearings are of spherical shape, and the spherical raceway surface of the housing washer is selfaligned. Thrust ball bearing can not stand the radial load, the extreme rotation speed is very low.
