Most of the thrust roller bearings are separable bearings, which are easy to install and disassemble. The rigidity of the bearing is larger. And occupy a small space, can withstand a large axial load and a certain amount of impact load, often used in the thrust ball bearing load capacity is insufficient in the workplace. However, the speed allowed by the bearing of this structure is relatively low. Thrust roller bearings can be divided into thrust cylindrical roller bearings, thrust tapered roller bearings and thrust roller bearings according to their structure.
Thrust needle roller bearings: The performance of thrust needle roller bearings is similar to that of thrust cylindrical roller bearings. But the axial size is smaller than the thrust cylindrical roller bearing, and the load capacity is larger. Because the length of the needle rolling is longer, the friction is larger and the speed is lower. Thrust needle roller bearings are divided into unidirectional needle roller bearings and bidirectional needle roller bearings according to the number of bearing roller rows. Unidirectional thrust needle roller bearings can withstand unidirectional axial load and limit axial displacement in one direction. The bidirectional thrust needle roller bearing can withstand the bidirectional axial load and limit the axial displacement in both directions. No Angle error is allowed when the thrust needle roller bearing is installed.
