What are the process requirements for metal based embedded solid self-lubricating bearings？

Due to the requirements of special production processes, some key equipment of industrial and mining enterprises operate under extremely harsh working conditions. Due to the heavy equipment, high environmental temperature, high dust, or acidic corrosive gases such as CO and SO2 in the air, there are many problems with the lubrication of the equipment, resulting in severe friction and wear. Up to now, of the above-mentioned enterprises in China still use traditional oil and grease lubrication, but in fact, these industrial and mining conditions have exceeded the scope of oil and grease lubrication, which easily leads to bearing and other friction pairs being bitten or killed, causing serious component wear and damage, and frequently to equipment shutdown.

To produce continuous operation, in addition to requiring the installation of multiple equipment for rotating repairs in the original design, a large number of maintenance personnel need to be invested. Severely restricting the improvement of productivity, spare parts, and energy consumption have become significant obstacles to the development of production. Enterprises such as automobile manufacturing, cement production, and petrochemicals have all proposed requirements for providing special lubricating materials under complex operating conditions.

Therefore, research on embedded self-lubricating composite materials has highlighted its characteristics in the material formulation and preparation process, and the material performance has reached the international advanced level, solving lubrication problems under special working conditions for enterprises and bringing obvious economic and social benefits. However, due to various reasons, more domestic enterprises have not yet adopted it, and the above situation still exists.
