Ball Bearing
 
A deep groove ball bearing is the most popular type of rolling-element bearing composed of an outer race, balls, an inner race and a bearing cage. And the race dimensions are close to balls dimensions. Usually, professional deep groove ball bearing manufacturers provide both single-row and double row deep groove ball bearings.

The materials for producing ball bearings are variety, including stainless steel, chrome steel and silicon nitride, etc. With a simpler construction comparing with other ball bearings, deep groove bearings are suitable for large quantity production.

The function of deep groove ball bearings is to reduce rotational friction. Those balls between outer race and inner race help avoid two flat surfaces rotating on each other, thus to achieve the purpose of lowering down friction coefficient. Additionally, deep groove ball bearings are primarily used to support radial loads; support both radial and axial loads is also possible. Comparing with a shallow-groove ball bearing, deep-groove bearings have higher load ratings for their size, but they are less tolerant of misalignment of the outer and inner races. Deep groove ball bearings, axial ball bearings and angular contact ball bearings are commonly used bearings for different uses.
