Thrust roller bearing is used to bear the combined axial and radial load dominated by axial load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction coefficient, higher speed and self-aligning performance.
The roller of the bearing is an asymmetric spherical roller, which can reduce the relative sliding between the roller and the raceway in the work. In addition, 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, and grease lubrication can be used in some low-speed cases. In the design and selection, priority should be given to the selection;
Thrust cylindrical roller bearing and thrust tapered roller bearing are suitable for low speed occasions. The speed of thrust tapered roller bearing is slightly higher than that of thrust cylindrical roller bearing. The thrust cylindrical roller bearing is a separate bearing, which can only bear unidirectional axial load and slight impact, and can limit the axial displacement of the shaft (or shell) in one direction. Therefore, it can be used for unidirectional axial positioning. However, its bearing capacity is much greater than that of thrust ball bearing. When the roller rolls, due to the different linear speeds at both ends of the roller, the roller will inevitably slide on the ring raceway. Therefore, the limit speed of this kind of bearing is lower than that of thrust ball bearing, which is usually only suitable for low-speed operation.
The standard design of thrust cylindrical roller bearing adopts turning metal solid cage. According to the requirements of users, other types or materials of cage can also be used. The thrust tapered roller bearing can only bear the unidirectional axial load and can limit the unidirectional axial displacement of the bearing, so it can be used for unidirectional axial positioning. Compared with the thrust cylindrical roller bearing, the bearing capacity is large, the relative sliding is small, but the limit speed is low.
