Deep Groove Ball Bearings

What is a deep groove 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.

Where could we use deep groove ball bearings?
Deep groove ball bearings can be used in wide range of applications.
Firstly, they can be used in industrial gearboxes. Existing gearboxes, if equipped with DEMY deep grove bearings, will be able to provide higher power rating.
Secondly, they are usually used in textile industry because DEMY bearings can meet the high running accuracy requirement in textile applications.
Thirdly, our bearings are ideal for industrial electrical motors. With an optimized contact geometry between the rolling elements and the raceways, our deep groove ball bearings can provide less friction and noise.
And additionally, you can find DEMY ball bearings in many motor vehicles and agricultural equipment, like automobiles, motorcycles, tractors, water pumps, precision instruments and so on.
