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:
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.
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:
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.
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.
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.
