SAE Standard Bimetallic Strips & Bearing Bush Type Lubricated Metal Thin-Wall
1. Product Description
SAE Standard Bimetallic Strips & Bearing Bush Type Lubricated Metal Thin-Wall is a bimetal bearing material in which bronze alloy comprise a two layer structure with a steel backing. This structure, whose mechanical strength is high, can be used under lubricated conditions and high-speed/high-load operation. It can be made from a variety of different materials, depending on the application, use conditions and lubrication.The surface copper alloy grades can be divided into high lead series, lead series and lead-free series.our self-lubricated bearing product have been supplied in chassis walking mechanism, body part, hydraulic etc.
