   Thrust  roller bearings are separable bearings, can only withstand axial load and a slight impact, to limit the shaft (or shell) of the 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. Roller rolling, because the roller ends of lines at different speeds, the roller raceway in the ring sliding inevitably arise, so such bearing speed limit lower than the thrust ball bearings, usually only for low speed applications. Standard design thrust cylindrical roller bearings with machined metal solid cage, according to user requirements, but also can be other types or material cage. Thrust tapered roller bearings can withstand axial load, one-way bearing to limit axial displacement, it can be used as a one-way axial positioning. And thrust cylindrical roller bearings, bearing capacity, sliding a small, but a lower speed limit. Thrust cylindrical roller bearings are mainly used for heavy-duty machine tools, power marine gear boxes, oil rig, electrical and other machinery in the vertical.
