How does a thrust ball bearing work?
Thrust ball bearing is a separable bearing. The shaft ring and seat ring can be separated from the cage and steel ball components. The shaft ring is a ferrule that matches the shaft, and the seat ring is a ferrule that matches the bearing seat hole, with a gap between it and the shaft. Thrust ball bearings can only bear axial loads, and one-way thrust ball bearings can only bear Axial loads in one direction, two-way thrust ball bearings can withstand axial loads in both directions; thrust ball bearings cannot limit the radial displacement of the shaft, and the limit speed is very low. One-way thrust ball bearings can limit one of the shaft and the housing. Axial displacement in two directions, bidirectional bearings can limit axial displacement in both directions. Thrust roller bearings are used to bear combined axial and radial loads where axial load is the main component, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has a lower friction factor, higher rotation speed, and has self-aligning performance. The rollers of the 29000 bearing are asymmetric spherical rollers, which can reduce the relative sliding of the rollers and raceways during operation. The rollers are long, large in diameter, large in number, and have high load capacity. They are usually oil lubricated. , grease lubrication can be used in individual low-speed situations. When designing and selecting, priority should be given to the use of type 80000 thrust cylindrical roller bearings, type 90000 thrust tapered roller bearings and type AXK thrust needle roller bearings, which can withstand unidirectional axial loads and are larger than thrust ball bearings. The load capacity is much larger, it is more rigid and takes up less axial space. Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low-speed applications. The speed of thrust tapered roller bearings is slightly higher than that of thrust cylindrical roller bearings.
