Thrust Ball Bearing Working Principle
- Sep 18, 2018 -

The thrust ball bearing is a separate type of bearing, and the shaft ring and the race ring can be separated from the components of the cage and the steel ball. The shaft ring is a ferrule that cooperates with the shaft. The seat ring is a ferrule that cooperates with the bearing housing hole, and there is a gap between the shaft; the thrust ball bearing can only bear the axial load, and the one-way thrust ball bearing can only bear Axial load in one direction, two-way thrust ball bearing can bear axial load in two directions; thrust ball bearing can not limit the radial displacement of the shaft, the limit speed is very low, one-way thrust ball bearing can limit one of the shaft and the housing The axial displacement of the direction, the two-way bearing can limit the axial displacement in both directions.


Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, this type of bearing has a low friction factor, a high rotational speed, and has a self-aligning performance. The stick of the 29000 type bearing is an asymmetrical spherical roller, which can reduce the relative sliding of the roller and the raceway during operation, and has a long roller, a large diameter, a large number of rollers, a high load capacity, and is usually oil lubricated. Individual low speed conditions can be lubricated with grease. In design selection, it should be preferred; 80000 thrust cylindrical roller bearing, 90000 thrust tapered roller bearing and AXK thrust needle roller bearing can withstand one-way axial load, which is more axial than thrust ball bearing. The load capacity is much larger, and the rigidity is large and the axial space is small. Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low speed applications. Thrust tapered roller bearings have a slightly higher rotational speed than thrust cylindrical roller bearings.
