Material
Bronze ( DIN-CuSn12 )
Graphite

Introduction
Solid lubricating bearings(CuSn12), made of tin bronze CuSn12 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.
