Description

Material Properties:

1.Combined with the wear resistance of copper alloy and high mechanical strength properties of steel;
2.Different cast copper alloy material is available according to work condition,including lower friction lead bronze;
3.The different coefficient of friction of the inner and outer material can protect the axil and rotating movement of the bearing in the housing under extremely high load with low
speed;
4.The solid lubricant plug can be embedded to achieve the self- lubricating performance ;
5.Compare with pure bronze bearing, the cost is reduced obviously;
6.The steel backing allowed to heat treatment to get high hardness, meanwhile the in layer can be re-machined if necessary;
7.The bronze layer can be casted on one or more layers to complex structure;
8.This material have same characteristic as pure bronze bearing, suitable for wide temperature range, different oil condition;

9.The RCB650GT have better mechanical load performance compare with bronze material,especially the impact strength.
