Compared with other thrust roller bearings, it has a lower friction coefficient, a higher rotational speed, and self - aligning performance.
The rollers of type 29000 bearings are asymmetric spherical rollers, which can reduce the relative sliding between the rollers and the raceways during operation. Moreover, the rollers are long, have a large diameter, and a large number of them are used, resulting in a high load capacity. Usually, oil lubrication is adopted, and grease lubrication can be used in some low - speed cases.
Type 80000 thrust cylindrical roller bearings, type 90000 thrust tapered roller bearings, and type AXK thrust needle roller bearings can withstand unidirectional axial loads. They have high rigidity and occupy a small axial space.
It can withstand relatively large axial loads, much greater than the axial load - bearing capacity of thrust ball bearings, making it suitable for heavy - load working conditions.
In heavy - duty machine tools, machining centers and other equipment, it provides stable support to ensure machining accuracy and the normal operation of the equipment.
