Product Description

Sintered Bronze bearings are all self-lubricating and maintenance free. The sintered bronze bushings consist of a porous bronze matrix impregnated with lubricant. The permissible sliding velocity for sintered bronze bushings is very high, which makes the bushings suitable for rotating applications

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.
