The Product Background, Production Technology And Technical Principles Of Copper Graphite Bearing

      Product Background:

      Solid inlaid copper graphite bearings (referred to as JDB) is a combination of metal bearing 

characteristics and oilless bearing characteristics of the new lubricating bearings, from the metal

matrix to withstand the load, the special formula of solid lubricating material from the 

lubrication. It has the characteristics of high carrying capacity, impact resistance, high 

temperature resistance and high self-lubricating ability. It is especially suitable for occasions 

such as heavy load, low speed, reciprocating or swinging and so difficult to lubricate and form oil 

film, and is not afraid of water erosion and other acid scouring. The current products have been 

widely used in metallurgical caster, rolling equipment, mining machinery, ships, steam turbines, 

turbines, injection molding machines and equipment production lines.

     Production Process:

      Due to the special requirements of the production process, some of the key equipment of 

industrial and mining enterprises in extremely harsh conditions to run. Due to heavy equipment, high 

ambient temperature, dust or air containing CO₂, SO₂ and other acidic corrosive gases, to the lubrication of the equipment to bring a lot of problems, friction and wear serious, so far, most

of the domestic enterprises still use the traditional oil, lubrication, and in fact these conditions

are beyond the oil, grease lubrication range, prone to bearing and other friction vice bites or 

killed, causing serious parts wear and damage, often lead to equipment outage.

    In order to produce continious operation, in addition to the original design requirements for 

the installation of multiple equipment gear repair, but also to invest a large number of maintenance 

personnel, seriously limiting the productivity increase, spare parts and energy consumption is 

great, has become an important obstacle to the development of production. Automobile manufacturing, 

cement production, petrochemical and other enterprises have proposed to provide complex conditions 

of special lubricating material requirements. To this end, the research on mosaic self-lubricating 

composites highlights its own characteristics in material formulation and preparation process. The 

material properties have reached the international advanced level, which has solved the problem of 

lubrication under special working conditions and brought obvious Economic and social benefits. But 

because of a variety of reasons more domestic enterprises have not yet adopted, the above situation

still exists.

      Technical Principle:

      The composite material used in the mosaic self-lubricating bearing is a new type of anti-

extreme pressure solid lubricating material consisting of a metal substrate and a solid lubricant 

paste embedded in the hole or groove of the substrate. In the process of friction metal substrates 

bear the vast majority of the load. The solid lubricant film, which is lubricated and firmly adhered 

and uniformly covered on the friction surface, is greatly reduced in friction and wear by the solid 

lubricant in the friction, hole or groove to the friction surface. With the friction, the embedded 

solid lubricant is constantly provided on the friction surface, ensuring long-term operation of the

friction on the good lubrication.
