BMB-1B bronze self lubrication bearing used tin bronze as base and agglomerated by bronze globular powderis made by surface rolling PTFE and high temperature resisting filling materials. It has very high coefficIent of Safety, particularly applicable for the locations of no stopping to repair in the course of continuous work and no adding oil at high temperature. At present. it has been widely applied to metallurgy steel industry, join casting machine square eadhen brick rolling way, furnace front equipment of high temperature furnace, cement grout pump and spiral conveyer. It may combine steel liner outside, or make turn-up, achieving the use effect of simultaneous friction of end and inner bore.
