推力球轴承是专为支持轴向力设计的，他们用于轴向力过高，可以由径向轴承传播(的地方)。
Thrust ball bearings are designed for supporting axial forces; they are employed where axial forces are too high to be transmitted by radial bearings.
轴承采用了单列向心推力球轴承，这种轴承具有同时承受较大的轴向荷载和径向荷载的能力。
Bearing a single row thrust ball bearings to the heart, which has at the same time to bear a greater bearing axial load and radial load capacity.
泵轴向力与径向力，均由轴承盒内所装单向推力球轴承，单列向心球轴承及滑动导轴所承受。
Axial Force and radial Force of the pump are bore by single-direction thrust ball bearing, single-row radial ball bearing and sliding guide axle.
