Deep Groove Ball Bearing is the common and widely used bearings for its simple structure and easy operation.

It can carry great radial load and a little axial load from all directions. it can carry relatively higher axial load. After being mounted on the shaft, the bearings serve a function to limit the axial displacement between shaft and bearing housing to the tolerance range. Compared to other kind of bearings, DGBB can be featured as low friction, high top rotating speed. It can be used, instead of thrust ball bearings, to carry great radial load in the situation that high rotating speed is required. Additionally, the rotating speed of this kind of bearings can be increased further if rubber, copper or duralumin is used in manufacturing the retainer.
