Deep groove ball bearings are relatively simple in structure and easy to use. They are the largest type of bearing with the largest production batch and the widest application range. It is mainly used to bear radial load and can also bear certain axial load. When the radial clearance of the bearing increases, it has the function of angular contact ball bearing and can withstand large axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction factor and a high limit speed. Thrust ball bearings can be used to bear the axial load when the speed is high.
It is the most representative rolling bearing with a wide range of uses. It is suitable for high-speed or even extremely high-speed operation, and is very durable without frequent maintenance. This type of bearing has low friction coefficient, high limit speed, simple structure, low manufacturing cost, and easy to achieve high manufacturing accuracy. Variety in size range and form, used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, yo-yo and other industries. It is the most widely used type of bearing in the machinery industry .
