What is the features of deep groove ball bearing double row?

The inner and outer ring raceways of deep groove ball bearing double row are arc-shaped deep grooves, and the radius of the groove is slightly larger than the radius of the ball. Mainly used to bear radial load, but also can bear certain axial load.

When the radial clearance of the bearing is enlarged, it has the function of angular contact ball bearing, which can bear larger axial load and is suitable for high-speed rotation. The bearing bearing double row can still work normally when the housing hole and the shaft are relatively inclined 8'-16', but its service life will be affected.

When the speed is high and thrust ball bearings are not suitable, this type of bearing can be used to bear pure axial load.

Deep groove ball bearing double row generally use a two-part steel stamping cage, but large-size or high-speed bearings use solid cages. This cage is guided by the ball like the stamping cage. The high-speed deep groove ball bearing retains The frame is usually guided by the inner ring or outer ring ribs.

Compared with other types of bearings of the same size, deep groove ball bearings have low friction coefficient, low vibration and noise, high limit speed, and high precision. They are the preferred bearing type for users when selecting models.

However, this type of bearing is not resistant to impact and is not suitable for heavy loads. Deep groove ball bearings are simple in structure and easy to use. They are a type of bearings with large production batches and a wide range of applications.

It is 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 output of bearings. It is a type of bearing with high output, common use and low price in our country.
