The copper sleeve acts as a bearing and belongs to sliding bearing class. The bearings are operated under sliding friction, and the relative shafts are rotated.Sliding bearings work smoothly, reliably and no noise. Under liquid lubrication conditions,the sliding surface is separated by the lubricating oil without direct contact, and also reduce the friction loss and surface wear.Oil film also has a certain role in vibration absorption with lubrication, heat dissipation, friction reduction and extended life. Copper bush is mainly used in machinery, printing and dyeing,papermaking, chemical, aerospace, coal, petroleum, automobile, marine machinery,engineering machinery, metallurgical and other industries.
1.axial thrust bearing ring is the machine parts and used in diesel engine, automobile, agricultural machinery,hydraulic machinery, machine tools, forestry machinery, engineering machinery, mining, railway, ship, petrochemical machinery, die casting machine,metallurgical equipment;
2.food packaging machinery, textile, light industry machinery and aviation, weapons,etc.
1.good corrosion resistance to its durability and long-term cost-effectiveness;
2.good mechanical properties from soft and ductile pure copper to manganese-bronze. Furthermore, almost all copper alloys castings maintain their mechanical properties at low temperatures , including impact toughness;
3.high thermal conductivity is greater than any metal except silver. Although the conductivity of copper decreases when alloyed, copper alloys with low conductivity still transmit heat and electricity better than other corrosion-resistant materials;
