Deep groove ball bearing is the most common type of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a steel ball and a group of cage. There are two kinds of single and double row deep groove ball bearing type, single row deep groove ball bearing type code is 6, double row deep groove ball bearing code 4. Its structure is simple, easy to use, is the production of the most common, the most widely used type of bearing.
working principle：
Deep groove ball bearings mainly bear radial load, also can bear radial load and axial load. When the radial load is only subjected to the radial load, the contact angle is zero. When deep groove ball bearings with a larger radial clearance, with angular contact bearing performance, can bear large axial load, deep groove ball bearing friction coefficient is small, the speed limit is also very high.
