Thrust roller bearings

      Thrust roller bearings are used to bear axial and radial combined loads mainly under axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed, and has self-aligning performance. The rollers are asymmetric spherical rollers, which can reduce the relative sliding between the rollers and the raceway during operation, and the rollers are long, large in diameter, large in number of rollers, and high in load capacity. They are usually lubricated by oil, and are available in individual low-speed situations. Grease lubrication.

      Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for occasions with low rotational speed, and the rotational speed of thrust tapered roller bearings is slightly higher than that of thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings, which can only bear one-way axial load and slight impact, and can limit the axial displacement of the shaft (or housing) in one direction, so they can be used for one-way axial positioning. But its carrying capacity is far greater than that of thrust ball bearings. When the rollers roll, due to the different linear speeds at both ends of the rollers, the rollers inevitably slide on the raceway of the ring. Therefore, the limit speed of this type of bearing is lower than that of the thrust ball bearing, 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 bear one-way axial load and can limit the one-way axial displacement of the bearing, so it can be used for one-way axial positioning. Compared with the thrust cylindrical roller bearing, the bearing capacity is large, the relative sliding is small, but the limit speed is lower.
