1 Special production process
Due to the special requirements of the production process, some key industrial and mining equipment in extremely harsh conditions to run. Due to heavy equipment, high ambient temperatures, dusty air with acidic or corrosive gases CO, SO2, etc., lubrication equipment has brought a lot of problems, severe friction and wear, as of now, most domestic companies still follow the traditional above-mentioned oil, greased, mining conditions which in fact are beyond the scope of oil, grease lubrication, prone to bearings and other friction bite or killed, causing severe wear and damage of parts, regularly result in equipment downtime. In order to produce continuous operation, in addition to the original design requires the installation of more than one equipment rotation, but also put a lot of maintenance personnel. This has seriously hampered the improvement of productivity and the enormous spare parts and energy consumption that have become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other companies have proposed to provide complex conditions under the conditions of special lubricants requirements. To this end, the study of mosaic self-lubricating composite material, highlighted on the material formulation and preparation of its own characteristics, material properties has reached the international advanced level, for enterprises to solve the problem of special conditions of lubrication, and has brought significant Economic and social benefits. However, due to a variety of reasons more domestic enterprises have not yet adopted, the above situation still exists.

2 key technical principles
Inlaid self-lubricating bearings with a composite material is a new type of anti-extreme pressure solid lubricating material, the metal substrate and embedded in the hole or groove of the solid lubricant paste composition. In the friction process, the metal substrate bear most of the load. The friction, hole or groove of the solid lubricant to the friction surface transfer or reverse transfer, the friction surface to form a well-lubricated, solid adhesion and uniform coverage of the solid transfer film, greatly reducing the friction and wear. As friction progresses, the embedded solid lubricant is continuously supplied to the friction surface to ensure good lubrication of the friction pair during long-term operation.
3. Water lubricated bearings detailed parameters
