大消费概念股 Compared with other bearings of the same size, the deep groove ball bearing has the advantages of small friction coefficient, low vibration and noise, high limit speed and high precision, which is the preferred bearing type for users.

The inner and outer raceways of deep groove ball bearings are all arc-shaped deep grooves, and the radius of raceway is slightly larger than that of ball. It is mainly used to bear radial load and also to bear certain axial load. When the radial clearance of the bearing increases, it has the function of angular contact ball bearing, can bear large axial load, and is suitable for high-speed rotation.
