Deep groove ball bearing, which is the most common used rolling bearing with simple structure and easy to use. Mainly used to bear radial load, it also can play the role of angular contact bearing and bear the connected load in radial and axial direction when the radial play of bearing is increased. When the rotation speed is very high and the thrust ball bearing is not suitable, the deep groove ball bearing can also be used to bear only axial load. Compared with other kinds of bearings of the same dimension, this kind of bearing has very small frictional coefficient and high limit rotation speed, but unable to endure impact and not suitable to endure heavy load. With the quality of durable and without having to be frequently maintained.
