Bimetallic bearing material, is a high quality cold rolled steel plate as the matrix, the surface sintering CuPb10Sn10 copper and lead alloy as the bearing surface material, and can be used according to the working conditions in the alloy layer surface processing of various types of oil groove, oil hole or oil hole, by rolling made of sliding bearing.
This kind of bearing not only has high fatigue strength, bearing capacity and impact resistance, but also has good corrosion resistance. It is suitable for medium-high speed under medium load, and for occasions with large impact load.

Technical information on the data sheet.

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 relative 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 for the application in question.
