products bases on alloy of bronze of special formula(CuZn24AL6).
The solid lubricating medium is inlaid in the friction surface and
the friction area of the solid lubricating medium take over 20%.The
combination of advantages of alloy of bronze and non-metal Friction
reducing matercing has broken in the limit
of general bearing that depend on oil film. It was widely used in
metallurgy, stell rollers in metallography, mineral machine, ships gas turbine
