It is based on a bronze alloy of a particular formulation with a sintered bronze layer as its interlayer and the compound of PTFE and Pb as its surface. It offers the property of good self-lubricating, low wear, and low fraction, it has made full use of the strong points of metals and polymer materials. It is used in steel metallurgical industry, cement grout pumps, and spiral conveyors for cement, etc.
It is based on a bronze alloy of a particular formulation with high density with a sintered bronze layer as its interlayer, with the compound of mostly PTFE and other factors. In accordance with an environmental request, it is without lead which makes the bearing lubricating condition cleaner.
