SF-1B is a triple layer composites bush, the base material being a bronze plate and film of heat resistant powder filled PTFE being calendered onto the sintered spherical bronze interlayer.

        SF-1B is of high safety factor, and is particularly appropriate for high temperature environment where no oil is efficient and where the machine must be under successivelong period working condition.

     This is widely used in steel metallurgy industry such as bushes for roller grooves of successive casting machines, cement grouting pumps and screw conveyers for cement.

    It can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions.
