1: Deep groove ball bearings are suitable for high speed or even extremely high speed operation, and are very durable without frequent maintenance.

2: Deep groove ball bearing this kind of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and easy to achieve high manufacturing accuracy.

3: Deep groove ball bearings are mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain angular contact ball bearing performance and can bear the combined radial and axial load.

4: After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or housing in both directions can be limited within the axial clearance range of the bearing, so it can be positioned in both directions.
