Thrust roller bearings are used to support axial and radial combined loads, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has lower friction factor, higher speed and self-aligning performance.
The standard design of the thrust cylindrical roller bearing adopts the metal solid cage of the vehicle, and other types or materials of the cage can be used according to the user's requirements. Thrust tapered roller bearings can only bear one-way axial load and can limit the axial displacement of the bearing in one direction, so it can be used as one-way axial positioning. Compared with the thrust cylindrical roller bearing, the bearing capacity is large and the relative sliding is small, but the limit speed is lower.
