Bimetal bushing is backing on low carbon steel, sintered with CuPb10Sn10 or CuSn6Zn6Pb3 bronze powder, which has the highest load capacity among the bi-metal bushings. the application including balance suspensions of heavy-duty trucks, track roller of bulldozers, auto chassis etc. 
It is a kindly of high load and low speed bushing, with wide application.

Bronze bushing  is a special wrapped bronze bearing with oil holes,it is a hollow cylindrical component, such as a tube and it is normally bipartite splited, with one, two or even no flange and used for axis elongation. They are parts subject to friction forces through rotation used in lightweight, heavy or super heavy machinery and equipment.
