The definition of strong fracture of ball bearings:
The strong fracture of deep groove ball bearings (inner and outer rings, steel balls, cages, sudden fracture) is mainly caused by stress exceeding the material strength limit, which is often caused by manufacturing defects, installation, overload during use, lubrication, and environmental degradation.

 

How to avoid strong fracture of deep groove ball bearings?

1. Choose appropriate cooperation.

2. Install bearings using appropriate methods.

3. Use appropriate tools or installation caps as needed.

4. Strictly follow the installation process and installation instructions.

5. Do not use brute force on bearings or apply installation force through rolling elements.

 

The following are common types of strong fractures

 

Using brute force installation or applying installation force to the steel ball can cause the outer ring of the bearing to break.

The impact during the installation of the bearing caused the outer ring sealing groove of the deep groove ball bearing to break.
