Thrust roller bearings (thrust roller bearings) are used to bear axial load-based shaft and radial combined load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has low friction coefficient, high speed and self-aligning performance. The roller of the 29000 bearing is an asymmetric spherical roller, which can reduce the relative sliding of the roller and the raceway in the work. The roller is long, the diameter is large, the number of rollers is large, and the load capacity is high. Oil lubrication is usually used. In the design and selection, should be preferred; 80000 type thrust cylindrical roller bearings, 90000 type thrust tapered roller bearings and AXK type thrust needle roller bearings, can bear one-way axial load, it is much larger than the thrust ball bearings axial load capacity, and rigid, occupy the axial space is small. Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low speed occasions, thrust tapered roller bearings speed slightly higher than the thrust cylindrical roller bearings.
