How should we deal with the rust situation of self-lubricating bearings

Author:admin   Date:2022-02-12
We should be no stranger to self-lubricating bearings, which are very common in our lives and are widely used, but some friends will find that self-lubricating bearings will cause rust and other phenomena due to different environments. So how should we deal with it?

If the bearing is rusted, it will affect the normal operation of the self-lubricating bearing, resulting in unnecessary losses.

Therefore, avoiding rust is necessary to maintain the bearing. "

First of all, in order to avoid rusting of self-lubricating bearings, the surface should be pretreated:

Appearance is boring:

After cleaning, it can be dried with filtered dry compressed air, or dried with a dryer at 120~170 °C, or dried with clean gauze.

Appearance clean:

Cleaning must be based on the nature of the surface of the anti-rust object and the current conditions, and an appropriate method must be selected. Commonly used are solvent cleaning, chemical disposal cleaning and mechanical cleaning.

In addition, anti-rust oil can also be applied. The detailed methods are as follows:

Brush method:

It is used for outdoor construction equipment or products with special shapes that are not suitable for immersion or spraying. When brushing self-lubricating bearings, pay attention not only to avoid accumulation, but also to avoid leakage.

Immersion method:

Some small items are immersed in anti-rust grease, so that a layer of anti-rust grease is adhered to the surface of the self-lubricating bearing. Oil film thickness can be achieved by controlling the temperature or viscosity of the anti-rust grease.

Spray method:

Some large rust preventives cannot be oiled by immersion method. Generally, the compressed air with a pressure of about 0.7Mpa is used to spray in the air cleaning center.

The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but perfect self-lubricating bearing fire prevention and labor maintenance measures must be adopted.

Well, the above is all about the introduction of the method of preventing self-lubricating bearings from rusting. I hope to help you.
