Introduction
Solid lubricating bearings(CuZn25Al5Mn4Fe3), made of special bronze CuZn25Al5Mn4Fe3 as base material, are produced by the process of being distributed special solid lubrication with certain angle and density. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of mold, metallurgy and engineering machinery due to the advantages of lead free, low friction coefficient, good self-lubricating,high working temperature and long life.
