Deep groove ball bearing is a rolling bearing in the most common type. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a group of retainer frame. Deep groove ball bearing type with single row and double row two, single row deep groove ball bearing type code 6, double row deep groove ball bearing 4. It has the advantages of simple structure,convenient use, is the production of the most common, the most widely used class of deep groove ball bearings mainly bear radial load, but also to support radial load and axial load. When its only bear the radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, has the properties of angular contact bearing, can bear large axial load,deep groove ball bearing friction coefficient is small, the limit speed is very high
