Self-lubricating bearing method for preventing rust

Copper-based solid inlaid self-lubricating bearings combine the wear resistance of copper alloys with the self-lubricating properties of solid lubricants, so that they do not require oil maintenance during use. If the self-lubricating bearing rusts, it will affect the normal operation of the self-lubricating bearing, resulting in unnecessary losses, then we must prevent it in advance. Below we introduce the method of self-lubricating bearings to prevent rust.
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-proof surface and At the time, select the appropriate method. 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. In addition, anti-rust oil can also be applied, as follows:

Soaking method:

Small small items are immersed in anti-rust grease to make them self-lubricating bearing surface Attach a layer of anti-rust grease. The oil film thickness can be achieved by controlling the temperature or viscosity of the rust preventive grease.

Brushing method:

Used for outdoor construction equipment or special-shaped products that are not suitable for soaking or spraying. Pay attention to the accumulation of self-lubricating bearings. Also pay attention to prevent leakage.

Spray method:

Some large-scale rust-proof materials cannot be oiled by immersion method, and generally sprayed with compressed air at a pressure of about 0.7 MPa in an air-cleaning place. 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.

Our factory specializes in the production of self-lubricating bearings. The main materials for the production of copper sleeves, graphite copper sleeves and self-lubricating bearings are brass, high-strength brass, aluminum bronze, tin bronze, zinc-based alloy, etc. Non-ferrous metals. In some manufacturers’ self-lubricating bearings, brass or aluminum bronze is used as the base to produce self-lubricating bearings. The use of the base is determined according to the actual working conditions.
