How to prevent and improve the rust of self-lubricating bearings
Author:admin Date:2022-02-17
We all know that rust and other phenomena on the surface of self-lubricating bearings will be caused due to the different environments in which self-lubricating bearings are located. So how can we maintain self-lubricating bearings to reduce a series of problems caused by the environment?
If the bearing is rusted, it will affect the normal operation of the self-lubricating bearing and cause unnecessary losses.
Therefore, preventing rust is necessary to maintain bearings. "
First of all, in order to prevent the self-lubricating bearing from rusting, the surface should be pretreated:
Surface dry:
After cleaning, it can be dried with filtered dry compressed air, or dried with a dryer at 120~170°C, or dried with a clean gauze.
Surface cleaning:
The cleaning method must be selected according to the nature of the surface of the antirust and the conditions at that time. Commonly used are solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method.
In addition, anti-rust oil can also be applied, the specific method is as follows:
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 for spraying in a clean air place.
The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but perfect self-lubricating bearing fire protection and labor protection measures must be adopted.
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, attention should be paid not only to avoid accumulation, but also to prevent leakage.
Immersion method:
Some small items are immersed in anti-rust grease, and a layer of anti-rust grease is adhered to the surface of their self-lubricating bearings. Oil film thickness can be achieved by controlling the temperature or viscosity of the anti-rust grease.
If the bearing is rusted, it will affect the normal operation of the self-lubricating bearing and cause unnecessary losses.
