What are the characteristics of deep groove ball bearings?

The deep groove ball bearing has the advantages of simple structure and convenient use, and is a kind of bearing with the largest production batch and the widest application range. Widely used in automobiles, home appliances, machine tools, motors, water pumps, agricultural machinery, textile machinery and many other fields. Its output accounts for more than 70% of the total bearing production, is the highest production in China, the most common use and the cheapest class of bearings.

The raceways of the inner and outer rings of the deep groove ball bearing are circular-shaped deep groove, and the radius of the groove is slightly larger than the radius of the ball. Mainly used to bear radial load, can also bear a certain axial load. When the radial clearance of the bearing is increased, it has the function of angular contact ball bearings, which can withstand large axial loads and is suitable for high-speed rotation. Bearing in the shell hole and shaft relative tilt 8 '~ 16', can still work normally, but affect its service life. In the case of high speed and not suitable for the use of thrust ball bearings can be used to bear the pure axial load.

Deep groove ball bearings generally use a steel plate stamping cage composed of two parts, but large size or high-speed bearings use solid cages, which are 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 the outer ring guard.

Compared with other types of bearings of the same size, deep groove ball bearings have small friction coefficient, low vibration and noise, high limit speed and high precision, and are the preferred bearing type for users. However, this type of bearing is not resistant to impact and is not suitable for bearing heavy loads.
