Methods to prevent self-lubricating bearings from rusting
First of all, in order to prevent the bearing from rusting, the surface should be pretreated:
Surface cleaning
Cleaning must be based on the nature of the surface of the anti-rust object And the conditions at that time, choose the appropriate method. Commonly used are solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method.
Surface drying
After cleaning, it can be dried with filtered dry compressed air, or dried with a dryer at 120~170°C, or with a clean Dry with gauze.
In addition, anti-rust oil can also be applied, the specific method is as follows:
Soaking method
Some small items are soaked in anti-rust grease, so that a layer of anti-rust grease is adhered to the surface. Oil film thickness can be achieved by controlling the temperature or viscosity of the anti-rust grease.
Brushing method
It is used for outdoor construction equipment or special-shaped products that are not suitable for immersion or spraying. When brushing, care should be taken not to generate accumulation , and also pay attention to prevent leakage.
Spray method
Some large rust preventives cannot be oiled by immersion method. Generally, it is carried out in a clean air place with filtered compressed air with a pressure of about 0.7Mpa. spray. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but perfect fire protection and labor protection measures must be adopted.
