CUSN8 Bushings is a tin bronze containing iron and manganese, which is of high strength and heat resistant. It has stable mechanical properties at high temperature (400℃), good friction reduction, good corrosion resistance in atmosphere, fresh water and sea water, good pressure processing under thermal state, heat treatment and strengthening, welding, not easy to fiber welding, and good machinability.

CuSn8 & CuSn6 Lubrication pockets tin bronze bushing is a maintenance-free composite sliding bearing with solid lubricant pockets, but primary lubrication is necessary. Therefore an aging resistant lithium stiffened grease should be used.
We have a large selection of plain and flanged bearings for various applications.
