Bearing repair methods:

1. Electric soldering iron repair: Use an electric soldering iron to heat the damaged part of the bearing, and then repair it with solder.

2. Welding repair: Use welding wire to repair the damaged part of the bearing, and then use tools such as files to trim it to restore it to its original state.

3. Spraying repair: Use high-speed arc spraying technology to spray metal or non-metallic materials on the surface of the bearing to repair the damaged part.

4. Overlay repair: This is a traditional repair method that restores the size and accuracy of the bearing by overlaying a layer of metal on the worn bearing position and then processing it.

5. Thermal spray repair: Heat the metal powder to a molten state and spray it on the worn bearing position to form a new metal coating to restore the size and accuracy of the bearing position.

6. Brush plating repair: Use brush plating technology to brush a layer of metal on the worn bearing position to restore the size and accuracy of the bearing position.

7. Laser cladding repair: Use laser cladding technology to clad a layer of metal on the worn bearing position to restore the size and accuracy of the bearing position.

8.BFSOS polymer material repair: Use polymer materials to apply on the worn bearing position to form a new protective layer to restore the size and accuracy of the bearing position. This method is simple to operate, low cost, and has a wide range of applications, but its durability and wear resistance are relatively low, and regular maintenance and replacement are required.
