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 tapered roller bearing: thrust tapered roller bearing inner and outer raceway is conical, the rolling body is also conical roller, and the extension lines of the three meet at the same point of the shaft line of the bearing. Therefore, the kinemical friction is smaller than that of other thrust roller bearings. Thrust tapered roller bearings do not allow error between shaft and bearing seat.
