Thrust roller bearings are used to support axial and radial combined loads, mainly axial loads, but the radial load must not exceed 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.

 

Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low speed applications. Thrust tapered roller bearings are slightly faster than thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings that can only withstand unidirectional axial loads and slight impacts. They can limit the axial displacement of the shaft (or housing) in one direction, so they can be used as unidirectional axial positioning. But its bearing capacity is far greater than thrust ball bearings. When the roller is rolling, due to the different linear speeds of the two ends of the roller, the roller inevitably slips on the raceway of the ring. Therefore, the limit speed of this type of bearing is lower than that of thrust ball bearings, and it is usually only suitable for low-speed operation.

 

Standard design of thrust cylindrical roller bearings adopts metal solid cages made of cars. According to user requirements, other types or materials of cages can also be used. Thrust tapered roller bearings can only withstand unidirectional axial loads and can limit the unidirectional axial displacement of the bearings, so they can be used as unidirectional axial positioning. Compared with thrust cylindrical roller bearings, the bearing capacity is large and the relative sliding is small, but the limiting speed is low.

 

Thrust cylindrical roller bearings are mainly used in heavy-duty machine tools, high-power marine gearboxes, oil rigs, vertical motors and other machinery.
