NSK Bearing Supplier Industrial Bearing 51440 Thrust Ball Bearing

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.

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. 

Main applications of thrust ball bearing:

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