Thrust roller bearing is used to bear axial and radial combined load, but the radial load should not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction coefficient, higher rotational speed and self-aligning performance.
The thrust cylindrical roller bearing and the thrust tapered roller bearing are suitable for the situation of low speed, and the speed of the thrust tapered roller bearing is slightly higher than that of the thrust cylindrical roller bearing. The thrust cylindrical roller bearing is a separate type bearing, which can only bear one-way axial load and slight impact, and can limit the axial displacement of shaft (or shell) in one direction, so it can be used as unidirectional axial positioning. But its bearing capacity is far greater than that of thrust ball bearing. Due to the different linear speeds at both ends of the roller, the roller will inevitably slide on the raceway of the ring when the roller is rolling. Therefore, the limit speed of this kind of bearing is lower than that of the thrust ball bearing, and it is usually only suitable for low-speed operation.
