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.
Thrust roller bearings are mainly used for heavy-duty machine tools, power marine gear boxes, oil rig, electrical
and other machinery in the vertical.
Thrust roller bearings are divided into Cylindrical roller thrust bearings, Needle roller thrust bearings, Tapered roller thrust bearings and Spherical roller thrust bearings. They are generally used to support combined load mainly consisting of axial load. But the radial load shall not exceed 55% of the axial load.
