Carbon sleeve bearing are employed where oil lubricated bearing cannot be used. Carbon, with its good dry running ability together with excellent corrosion resistance, form retention and resistance to high temp. and sudden temp changes as well as good thermal conductivity, possess an outstanding combination properties for these application.carbon bearing can be pressed into a process of h7/s6 for operating temperature of up to 1500c. the housing or steel ring should be heated up to about 4500c. the housing or steel ring should be heated up to about 4500c for shrinking in.
