A deep groove ball bearing is the most commonly used rolling bearing. Its structure is simple and easy to use. Mainly used to bear radial load, but when increasing the bearing radial clearance, has a certain angular contact ball bearing performance, and can withstand the diameter, and axial combined load. At the high speed and should not use thrust ball bearing, also can be used to bear pure axial load. With deep groove ball bearing specifications of the same size as other types of bearings, such bearings’ friction coefficient is small, high limit speed. But not shock-resistant, and not suitable for heavy loads.
In addition to the basic type of deep groove ball bearings, there are various variations of structure, such as deep groove ball bearings with dust cover, deep groove ball bearings with a rubber seal, deep groove ball bearings with a stop groove, etc.
