The Thrust Ball Bearings is classified into two kinds: unidirectional thrust bearing and bidirectional thrust bearing. The former can bear the axial force in one direction and the latter can bear he axial forces in two directions. Neither unidirectional nor bidirectional thrust ball bearings could bear any radial force.
The Thrust Ball Bearing has strict requirements for the difference of thickness between the groove and end faces (i.e. shaft and housing ring). Its product precision can reach up to the grade of P4.
Based on our failure analysis to the Thrust Ball Bearing, the working speed and load are highly recommended to concern during the model selection. Especially when the working speed is high, the axial force should be maintained to prevent the steel balls from sliding radially under the action of the centrifugal force, which may result in a bearing damage in early stage.
