Thrust roller bearing

Thrust roller bearings are used to support axial and radial combined loads that are 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 factor. High speed and self-aligning performance.

29000 type rollers are asymmetric spherical rollers, which can reduce the relative sliding of rollers and raceways during work, and have long rollers, large diameters, a large number of rollers, high load capacity, and usually oil lubrication , Individual low-speed situations can be lubricated with grease. When designing and selecting, it should be preferred;

80000 thrust cylindrical roller bearings, 90000 thrust tapered roller bearings and AXK thrust needle bearings, can withstand unidirectional axial load, it has much greater axial load capacity than thrust ball bearings, and has greater rigidity, Takes up little axial space.

Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low speed applications. Thrust tapered roller bearings have a slightly higher speed than thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings and can only withstand unidirectional axial loads and slight impacts. They can limit axial displacement in one direction of the shaft, 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 bear unidirectional axial loads and can limit the unidirectional axial displacement of the bearing. Therefore, they can be used as unidirectional axial positioning. Compared with thrust cylindrical roller bearings, they have larger bearing capacity and less relative sliding. But the limit speed is low.
