Structure characteristics of deep groove ball bearing

Structure characteristics of deep groove ball bearing. The raceways of the inner and outer rings of deep groove ball bearings are circular arc shaped deep grooves, and the raceway radius is slightly larger than the ball radius. 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, which can bear larger axial load and is suitable for high-speed rotation. The bearing can still work normally when the housing hole and shaft are inclined 8 '~16' relatively, but its service life is affected. This type of bearing can be used to bear pure axial load when the speed is high and thrust ball bearing is not suitable. Deep groove ball bearings generally use a steel plate press cage composed of two parts, but large size or high-speed bearings use solid cages. This cage is guided by the ball as the press cage, and the cage of high-speed deep groove ball bearings is usually guided by the inner ring or outer ring rib. Compared with other types of bearings with the same size, the deep groove ball bearing has small friction coefficient, low vibration and noise, high limit speed, and high accuracy, so it is the preferred bearing type for users to select. However, this type of bearing is not impact resistant and is not suitable for bearing heavy loads. The deep groove ball bearing is simple in structure and convenient in use. It is a kind of bearing with large production volume and wide application range. It is widely used in automobiles, household appliances, machine tools, motors, water pumps, agricultural machinery, textile machinery and many other fields. Its output accounts for more than 70% of the total output of bearings. It is a kind of bearing with higher output, more common use and lower price in China.
