SF-1B is of high safety
factor, and is particularly appropriate for high
temperature environment where the machine must be
under successive long 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.
