Introduction to the characteristics of thrust roller bearings

thrust roller bearings are 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

29000, the rod of the type bearing is an asymmetric spherical roller, which can reduce the relative sliding of the roller and the raceway in the work. Moreover, the roller is long, the diameter is large, the number of rollers is large, and the load capacity is high. It is usually lubricated by oil, and grease lubrication can be used in some low-speed situations. In the design and selection, priority should be given to selection

80000 thrust cylindrical roller bearing, 90000 thrust tapered roller bearing and AXK thrust needle roller bearing can bear one-way axial load, which is much larger than the axial load capacity of thrust ball bearing, and has large rigidity and takes up less axial space

thrust cylindrical roller bearings and thrust roller bearings are suitable for occasions with low speed, and the speed of thrust tapered roller bearings is slightly higher than that of thrust cylindrical roller bearings

the thrust cylindrical roller bearing is a separate bearing, which can only withstand one-way axial load and wear products, which will be taken away by the lubricating oil for slight impact, and can limit the axial displacement of the shaft (or shell) in one direction, so it can be used for one-way axial positioning. But its bearing capacity is far greater than that of thrust ball bearings. When the roller rolls, due to the different linear speeds at both ends of the roller, the roller inevitably slides on the race. Therefore, the limit speed of this kind of bearing is lower than that of thrust ball bearing, and it is usually only suitable for low-speed operation

the thrust cylindrical roller bearing of standard design adopts turning metal solid cages, and cages of other types or materials can also be used according to user requirements. The thrust tapered roller bearing can only bear one-way axial load. It is suggested that we should pay more attention to quality and production standards, strengthen the convergence of industrial talents, and limit the one-way axial displacement of the bearing, so it can be used for one-way axial positioning. Compared with thrust cylindrical roller bearings, the bearing capacity is large, the relative slip is small, but the limit speed is low
