bearing stick asymmetric spherical roller


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 speed available greased . In the design selection , should be preferred ;
80000 -type cylindrical roller Wind turbine bearing thrust bearings , 90000 Thrust tapered roller bearings and needle roller thrust bearings AXK type , can withstand a one-way axial load, it is much larger than the thrust ball bearing axial load capacity and rigidity, small axial space occupied .
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 automotive bearing 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.
Standard design thrust cylindrical roller bearings with machined metal solid cage, according to user requirements , but also other types or materials cage. Thrust tapered roller bearings can withstand axial load, can limit the axial displacement of the bearing , it can be used as a one-way axial positioning . And thrust cylindrical roller bearings compared to carrying capacity, relative sliding is small, but the lower speed limit
