Thrust tapered roller bearings and thrust roller bearings are separated type bearings, bearing more rigid and take up less space, able to withstand a large axial load,generally used when using oil lubrication.Thrust Ball Bearings are applied to machine elements which bear single side axial load and with the lower the mechanical speed, such as crane hooks, immediately water pumps, immediately centrifuges, jacks, low-speed reducer and so on.
