Thrust roller bearing

Thrust roller bearings are used to withstand axial and radial combined loads, with the radial load not exceeding 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has a lower friction coefficient, higher speed, and has self-aligning performance.
The rollers of the bearing are asymmetric spherical rollers, which can reduce the relative sliding between the rollers and the raceway during operation. The rollers are long, have a large diameter, have a large number of rollers, and have a high load capacity. Oil lubrication is usually used, and in some low-speed situations, grease lubrication can be used. When designing and selecting, priority should be given to selecting;
Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low-speed applications, with thrust tapered roller bearings having slightly higher speeds than thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings that can only withstand unidirectional axial loads and slight impacts, and can limit the axial displacement of the shaft (or housing) in one direction. Therefore, they can be used for unidirectional axial positioning. But its load-bearing capacity is much greater than that of thrust ball bearings. When the roller rolls, due to the different linear velocities at both ends of the roller, the roller inevitably slides on the raceway of the ring. Therefore, the maximum speed of this type of bearing is lower than that of thrust ball bearings, and it is usually only suitable for low-speed operation.
The standard designed thrust cylindrical roller bearing adopts a car made metal solid cage, and other types or materials of cages can also be used according to user requirements. Thrust tapered roller bearings can only withstand unidirectional axial loads and can limit the unidirectional axial displacement of the bearing, so they can be used for unidirectional axial positioning. Compared with thrust cylindrical roller bearings, it has a higher load-bearing capacity and smaller relative sliding, but has a lower limit speed.
