Explain in detail the causes and prevention methods of eccentric bearing corrosion

The corrosion of eccentric bearing is caused by various internal and external factors, which can be summarized as follows:

1. The surface finish of the metal (poor oxygen concentration, battery corrosion).

2. The chemical composition and structure of the metal material itself.

3. The composition and pH value of the solution in contact with the metal surface;

4. Ambient temperature and humidity.

5. Various environmental media in contact with metal surfaces.

6. Other people's sweat is also the cause of bearing corrosion, and its pH value is 5~6. Therefore, in order to prevent corrosion caused by hand sweat, installation and production personnel should wear gloves and do not touch the imported bearings with their hands.

Apply anti-rust oil to prevent eccentric bearings from rusting

1. Soaking method: Some small imported bearings are immersed in anti-rust grease. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease. A method of sticking a layer of anti-rust grease on the surface.

2. Brushing method: When brushing, pay attention to evenly smear the surface of the imported bearing, not to accumulate, but also to prevent leakage.

3. Spray method: Some large anti-rust materials are not suitable for oiling by immersion method. Generally, use filtered compressed air with a pressure of about 0.7Mpa for spraying in a clean air place. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil. This method must adopt perfect fire prevention and labor protection measures.
