Bimetallic Bearing Vehicles Bushings CuPb10Sn10 Or CuSn6Zn6Pb3
Bimetallic bearing bushings for vehicles, specifically CuPb10Sn10 or CuSn6Zn6Pb3 alloys, are designed to provide superior performance in automotive applications. These bushings consist of a base metal layer bonded to a wear-resistant alloy layer, creating a unique bimetallic construction.
The CuPb10Sn10 alloy, also known as leaded tin bronze, offers excellent wear resistance and lubricity. The lead content provides self-lubricating properties, reducing friction and wear during operation. This alloy is commonly used in automotive bushings and bearings where smooth and reliable operation is crucial.
The CuSn6Zn6Pb3 alloy, also known as high-lead tin bronze, exhibits similar properties to CuPb10Sn10 but with a slightly different composition. It provides excellent wear resistance, lubricity, and corrosion resistance, making it suitable for demanding automotive applications.
The bimetallic construction of these bushings combines the strength and durability of the base metal with the wear resistance and self-lubricating properties of the alloy layer. This ensures smooth operation, reduced maintenance requirements, and extended service life in various vehicle applications.
Our range of bimetallic bearing bushings for vehicles includes CuPb10Sn10 and CuSn6Zn6Pb3 alloys in various sizes and specifications to meet your specific requirements. We offer customized solutions to ensure the perfect fit and performance for your automotive application.

Characteristics
Bimetal-bearing is a bimetal bearing, wrapped of steel sheets with a layer of lead bronze.
The standard sizes are fitted with lubrication indents on the running surface. For standard bearings is normally the steel backing copper plated to improve the corrosion resistance. The layer of lead bronze makes it possible to use these bearings with relatively long lubrication intervals.
Bimetal-bearings can be manufactured with a thicker lead bronze layer for applications where the bearing has to be machined after mounting. The material of the layer can be fitted to the special needs of the application in question.
