If the bearing rusts, it will affect the normal operation of the self-lubricating bearing, resulting in unnecessary losses.
Therefore, preventing rust is necessary to maintain the bearings. ”
First of all, in order to prevent the self-lubricating bearing from rusting, the surface should be pretreated:
Surface cleaning:
Cleaning must be based on the nature of the surface of the rust preventive and the conditions at the time. Commonly used are solvent cleaning, chemical cleaning and mechanical cleaning.
Dry surface:
After cleaning, dry it with filtered dry compressed air, or dry it with a dryer at 120~170 °C, or dry it with clean gauze.
Self lubricating bearing
In addition, anti-rust oil can also be applied, as follows:
Soaking method:
Some small items are immersed in anti-rust grease to adhere a layer of anti-rust grease to the surface of the self-lubricating bearing. The oil film thickness can be achieved by controlling the temperature or viscosity of the rust preventive grease.
Brushing method:
For outdoor construction equipment or special-shaped products that are not suitable for soaking or spraying, self-lubricating bearings should be brushed with care not to accumulate, but also to prevent leakage.
Spray method:
Some large rust preventives cannot be oiled by immersion, and are generally sprayed in an air clean place with filtered compressed air at a pressure of about 0.7 MPa.
The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but it must adopt perfect self-lubricating bearing fireproof and labor protection measures.
