It is made of a high-quality, low-carbon steel plate, sintered porous bronze as its interlayer and the compound of PTFE and Pb as its surface. It offers the property of good self-lubricating, low wear, and a low fraction. It has made the full use of the strong points of metals and polymer materials. It is used in printing machines, woven machines, tobacco machines, as well as gymnastic machines etc.
It is made of a high-quality, low-carbon steel plate, sintered porous bronze as it's interlayer and the compound of PTFE material and Pb as its surface. In accordance with an environmental request, it is without lead which makes the bearing lubricating condition cleaner. It is based on a bronze alloy of a particular formulation with high density with the sintered bronze layer as its interlayer, with the compound of mostly PTFE and other factors.
