The deep groove ball bearing is a kind of rolling bearing with most representatives, and it has features of small friction coefficient, high limiting speeds, simple structure, low cost, and high manufacturing precision. It has various sizes and structures, and is used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, and a kind of bearing with most applications in the machinery industry. The bearing can bear mainly the radial load, but also can bear a certain axial load.


With larger radial clearance, the axial carrying load can be increased. When it only bears the radial load, the contact angle should be zero; when it bears an axial load, the contact angle should be greater than zero. A stamped ribbon cage is commonly machined as the solid cage; sometimes the nylon cage can also be used.


After the deep groove ball bearing is mounted on the shaft, within the axial clearance of the bearing, the axial displacement of the shaft or the housing in both directions can be limited, so it can be used for axial positioning in both directions. In addition, the bearing has also some self-aligning capability; when it is tilted to 2' ~ 10' corresponding to the housing, it still can be operated normally, but there may be a certain influence on the bearing life. The deep groove ball bearing cage is commonly the stamped steel ribbon shape, and the machined metal solid cage is also used for large bearing.


The deep groove ball bearing is the most commonly used rolling bearing. It has simple structure and is easy to use. It is mainly used to bear the radial load; when the radial clearance of bearing is increased, it will show a certain performances of the angular contact ball bearing and can withstand radial and axial integrated load. When the speed it too high and the thrust ball bearing can not be used, it can also bear only the axial load. Compared with other types of bearings with the same sizes, it has small friction coefficient and a high limiting speeds, but it can not bear the impact and is not suitable to bear a big load.
