Structural features of deep groove ball bearings

Structural features of deep groove ball bearings. The inner and outer ring raceways of deep groove ball bearings are both arc-shaped deep grooves, and the groove radius is slightly larger than the ball radius. It is mainly used to bear radial loads and can also bear certain axial loads. When the radial clearance of the bearing increases, it has the function of an angular contact ball bearing, can bear large axial loads, and is suitable for high-speed rotation. The bearing can still work normally when the housing hole and the shaft are relatively tilted by 8′ to 16′, but its service life is affected.
This type of bearing can be used to bear pure axial loads when the speed is high and thrust ball bearings are not suitable. Deep groove ball bearings generally use a steel plate stamping cage composed of two parts, but large-sized or high-speed bearings use solid cages. This cage is guided by the ball like the stamping 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 of the same size, deep groove ball bearings have a small friction coefficient, low vibration and noise, high limit speed, and high precision. They are the preferred bearing type when users select.
However, this type of bearing is not impact-resistant and is not suitable for bearing heavier loads. Deep groove ball bearings have a simple structure and are easy to use. They are a type of bearing with a large production volume and a wide range of applications. They are widely used in many fields such as automobiles, home appliances, machine tools, motors, water pumps, agricultural machinery, textile machinery, etc. Their output accounts for more than 70% of the total output of bearings. They are a type of bearing with a high output, a common use and a low price in my country.
