Thrust roller bearings are separable bearings, can only withstand axial load and a slight impact, to limit the shaft (or shell) ofthe axial displacement in one direction, it can be used as single-axis to the position.
But its carrying capacity is far greater than the thrust ball bearings. Thrust roller bearings are mainly used for heavy-duty machine tools, power marine gear boxes, oil rig, electrical and other machinery in the vertical.
