Today, let us learn about a new ball bearing. The angular contact ball bearing is known as radial thrust ball bearing. Because it can load many steel balls, the load capacity of its diameter is greater than that of the common bearing. At the same time it can support a very great axial load or pure axial load. To some degree, its working rotate speed is similar to that of deep groove ball bearing but its strength is more intensive than the deep groove one. When people install Angular Contact Ball Bearings, it must be set up accurately because this bearing is very sensitive to the error of the axial line. In the common situation, this bearing is not used to alone support the radial load. If it is used to bear the radial load, it must increase the axial load.
There are a lot of types for Small Deep Groove Ball Bearings and they are widely used in many different places. In order to meet the industrial need, the angle of contact for this ball bearing is often produced into three series namely 15°, 25° and 40°. The bigger the angle of contact is, the higher the axial load is. But in the condition with a high speed it is better to adopt the small angle. Besides, this kind of the bearings also can be classified into separated-type and inseparable type. Because the condition for installation is limited, it is required to remove the outside ring or inside ring from the whole set bearing.
