Smearing anti-rust oil on bearing to prevent rust

Bearing corrosion is commonly in operation process. Following are some method to prevent bearing corrosion.

1. Immersion method.

Some small bearings could be immersed in anti-rust grease. Thickness of oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease. Making the bearing surface adhere to a layer of anti-rust grease to achieve anti-rust effect.

2. Brush coating method

Spreading on the bearing surface evenly, do not pile up, but also pay attention to prevent leakage.

3. Spray method

For some large bearings, they generally sprayed in clean air with filtered compressed air with a pressure of about 0.7Mpa. 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.

Method to remove rust from bearing surface.

1. Surface cleaning.

Cleaning must be combined with the nature of the bearing surface and the prevailing conditions.  Solvent cleaning, mechanical cleaning, and chemical treatment cleaning are the most common method to remove surface rust.

2. Dry surface

It can be dried with filtered dry compressed air. Or using a dryer during 120~170℃, and finally wipe dry with a clean gauze.
