Deep groove ball bearings mainly take radial load as well as take moderate axial load. With less coefficient of friction, high limiting speed, large size range and variations of structure, they are suitable for precision instruments, low noise motors, automobiles, motorcycles, and other common machinery, as a widely used type of bearings in machinery industry.

Feartures:                                        
1. Low density. As the rolling body density decreases, high-speed operation of its centrifugal load is also reduced, which can work at higher speed.                                        
2. Moderate elastic modulus. Elastic modulus is too large due to stress concentration and reduce the bearing capacity of the bushing.                                        
3. Thermal expansion coefficient is small. Reduce the sensitivity to temperature changes, so that the bearing operating temperature range is wider.                                        
4. High compressive strength. High compressive strength is the need for high stress for rolling bearings.                                        
5. High hardness and high toughness. These two properties combine to achieve better surface roughness; and can prevent external particles and shock damage.                                        
6. Good anti-rolling contact fatigue and has a peel failure mode.                                        
7. Special occasions should have high temperature, corrosion resistance and stability.
