Product Description

Bimetal bushing is backing on low carbon steel, sintered with aluminum 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.
