How to prevent self lubricating bearing from rusting

Because of the different environment, self-lubricating bearing will cause rust and other phenomena.
If the bearing is rusty, it will affect the normal operation of self-lubricating bearing and cause unnecessary loss.
Therefore, it is necessary to prevent rust in the maintenance of bearings. "
First of all, in order to prevent self-lubricating bearing from rusting, the surface should be pretreated as follows:
Surface cleaning:
The proper cleaning method must be selected according to the nature of the surface and the conditions at that time. Generally, there 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 120 ~ 170 ℃ dryer, or wiped with clean gauze.

In addition, antirust oil can be applied as follows:
Soaking method:
Some small items are immersed in antirust grease to make the self-lubricating bearing surface adhere to a layer of antirust grease. The oil film thickness can be achieved by controlling the temperature or viscosity of anti rust grease.
Brush coating method:
For outdoor construction equipment or products with special shape that are not suitable for soaking or spraying, attention should be paid not only to avoid accumulation, but also to prevent coating leakage.
Spray method:
Some large-scale antirust materials can not be oiled by immersion method. Generally, filtered compressed air with a pressure of about 0.7MPa is used for spraying in the air clean place.
Spray method is suitable for solvent dilution antirust oil or thin layer antirust oil, but must adopt perfect self-lubricating bearing fire protection and labor protection measures.
