Thrust ball bearings are designed to take axial (thrust) loads at high speeds, but they cannot take any radial loads. These bearings feature bearing washers with raceway grooves in which the balls move. 

Structure:

The thrust ball bearing is composed of race,shaft washer and steel ball retainer.The one that matches with the axis is called washer.The one that matches with the shell is called the ring.

Thrust ball bearing is a kind of separation bearing. The shaft ring and seat ring can be separated from the cage and steel ball components.

Thrust ball bearing is designed to withstand thrust load at high speed and is composed of a gasket-shaped ring with a ball rolling groove.Owing to its cushion-shape ring,the thrust ball bearing is divided into flat-base cushion type and aligning spherical surface cushion type.

Bearing role:

Its role should be to support, that is, literal interpretation used to bear the shaft, but this is only a part of its role, support its essence is able to bear radial load.

The lubrication method of bearings is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication prevails.

Main applications of thrust ball bearing:

Crane hook, vertical water pump, vertical centrifuge, jack, low speed reducer, etc.

Small thrust ball bearing seat ring and shaft ring inner diameter size difference is very small, there is no obvious difference between the two bundles. In order to prevent the phenomenon of mixed sleeves, that is, a set of bearings installed are found to be both seat rings or shaft rings. This requires certain measures. Usually, the drawing ring and the seat group are distinguished by auxiliary tooling when the set is closed, or the inner diameter plug gauge is used to check the inner diameter size before sampling the nominal height. In order to check the inner diameter, the seat ring is placed below and the shaft ring is placed above. If the inner diameter of the seat has obvious quenching heating oxidation color or is not grinding, there is no need to test the inner diameter size, and the difference between the shaft ring and the seat can be clearly seen, and it is not easy to mix. After assembling the thrust ball bearing, the nominal height T should be measured to confirm whether it is qualified. When measuring, calibrate with height block or standard parts, and measure the load, the bearing needs to rotate dozens of times, and be sure to reach the minimum height.
