What is the role of trust ball bearing and thrust roller bearing’s axial thrust load?

Thrust ball bearing is a separate type of bearing. The shaft ring and the seat ring can be separated from the components of the cage ball. The shaft ring is a ferrule that fits with the shaft, and the seat ring is a ferrule that cooperates with the bearing housing hole, and has a gap between the shaft. axial thrust load of Thrust ball bearings can only draw axial thrust load. One-way thrust ball bearings can only bear the axial thrust load of one room. Two-way thrust ball bearings can bear axial thrust load in two directions. The thrust ball can not restrain the warp direction of the shaft to move, and the limit speed is very low. The one-way thrust ball bearing can limit the axial displacement of the shaft and the housing in one direction, and the two-way bearing can limit the axial displacement in both directions.

Thrust roller bearings are used to support axial load-based shafts, warp joint loads, but warp axial thrust load must not exceed axial thrust load 55% of axial loads. Compared with other thrust roller bearings, this type The bearing has a low friction coefficient, a high rotational speed, and has a self-aligning ability. The 29000-type bearing is rolled into an asymmetrical ball m roller, which can reduce the relative movement of the stick and the raceway during operation, and the roller has a long diameter.The number of rollers is large and the axial thrust load capacity is large, usually oil lubrication, and the individual low speed conditions can be lubricated with grease. When designing the selection, it should be preferred.
