Product description

Copper bushings usually are used to be reduced the wear,corrosion and noise in the production .It also makes the machine easily to repair, and simplifies the complex production process.To use the copper bushings can reduce the friction of parts,avoid to wear. Usually we just need to change the copper bushings if the parts wear,that can save the cost.  

The copper bushings are working under sliding friction situation,belongs to sliding bearing category.  Generally need to cooperate with lubrication system to complete the work. The sliding bearing works smoothly,reliably and noiselessly.After the liquid lubricating,the sliding surfaces are separated and avoid contacting directly.The surface will form the oil film,which has the advantages of vibration absorption, lubrication, heat dissipation, friction reduction and life extension. That will reduce the friction loss and the surfaces wear.  

characteristics of the copper bushings:

Wear resistance --- Overall,the wear resistance of copper bushing is better.Different material has different characteristics.The inner parts of the copper bushing are very closer and no pores , sand holes.So the color of the copper bushing is special ,and it looks bright relatively.And the most important thing is the hardness of copper bushing is also very high.

Corrosion resistance --- The corrosion resistance of copper bushing is very well. It is mainly used in the atmosphere and freshwater environment,where can not easy to seize.Copper bushing has the chemical elements of dilute sulfuric acid, hydrochloric acid and fatty acids, so the corrosion resistance of copper bushing is very good. If there is no lubricant and water, it can still work normally. And the sliding and self-lubricating can still be maintained.

Pressure resistance ---The pressure resistance of the copper sleeve is also pretty good. Its surface pressure is very large, and it can well withstand the lateral pressure of the bearing.In the case of high load pressure, the copper bushing can also be operated, which is suitable for the low speed and heavy load situation .

Copper sleeve processing technology : sand casting, metal casting, centrifugal casting, precision casting, pressure casting, vacuum casting
