How does the thrust ball bearing work?

Working principle
The thrust ball bearing is a separation bearing, a bearing, a race, and a casing, and a component of the steel ball. The axle is a ferrule with the axis, and the seat is a ferrule that cooperates with the bearing seat hole, and there is a gap between the shafts; the thrust ball bearing can only withstand the axial load, the one-way thrust ball bearing can only bear The axial load of one direction, the bidirectional thrust ball bearing can withstand the axial load in both directions; the thrust ball bearing cannot limit the radial displacement of the shaft, the limit speed is very low, the one-way thrust ball bearing can limit the shaft and the housing The axial displacement of the direction can limit axial displacement in both directions.

The thrust roller bearing is used to withstand the axial load-bearing axis, radially joint load, but the radial load must not exceed 55% of the axial load. Such bearing factors are lower than other thrust roller bearings, high speed, and have a calorie performance. The 29,000-type bearing stick is a non-symmetrical spherical roller, which can reduce the relative slide of the roller and the raceway, and the roller is long, the diameter is large, the number of rollers is large, the load capacity is high, usually oil lubrication, Individual low speed can be lubricated. When designing selection, it should be preferred; 80000 thrust cylindrical roller bearings, 90000 thrust tapered roller bearings and Axk type thrust roller bearings, can withstand the unidirectional axial load, which is more axial than the axial direction of the thrust ball The load capacity is much larger, and the rigidity is large, and the axial space is small. The thrust cylindrical roller bearing and thrust needle bearing is suitable for use in low speed, and the thrust cone roller bearing speed is slightly higher than the thrust cylindrical roller bearing.
