Thrust roller bearings for axial load mainly axial , radial joint load , but the radial load should not exceed 55% of the axial load . Other thrust roller bearings, such bearings lower friction coefficient , high speed, and aligning performance .
    29000 bearing stick asymmetric spherical roller , the roller can reduce the relative sliding and rolling in the work , and the roller length , large diameter roller quantity, high load capacity, usually oil lubrication , individual low speeds available greased . In the design selection , should be preferred ; 80000 -type cylindrical roller thrust bearings , 90000 Thrust tapered roller bearings and needle roller thrust bearings AXK type , rigidity, axial occupy a small space. Thrust cylindrical roller bearings and thrust roller bearings for low speed applications , thrust tapered roller bearing speed slightly higher than the thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings, can withstand axial load and a slight impact, to limit the axial displacement ( or shell ) in one direction , and therefore can be used as a one-way axial positioning . But its carrying capacity is far greater than thrust ball bearings. Roller rolling , because the roller ends of lines at different speeds , so that the rollers in the ring raceway sliding inevitably arise , therefore , such a bearing speed limit lower than the thrust ball bearings , normally only for low speed applications.
