Technical information on the datasheet.
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.
Material Structure
Metal backed with bronze graphite oilless bearings
1. Sinter bronze with graphite– Liner material: CuPb10Sn10.Good wear resistance with lower friction and excellent load-carrying capacity. The bimetallic bushing can be machined after fitting to get precision tolerance. We also can supply the bearings with PTFE or graphite sprayed layer on the work surface to get much lower start friction.
2. Metal backing –low carbon steel: gives exceptionally high load carrying capacity, excellent heat dissipation.
3. Copper plating 0.002mm, good corrosion resistance.
Due to the stability of the matrix is low carbon steel material, the machining accuracy of the outer diameter of the shaft sleeve is guaranteed, and there is no need for screw fixation after the product is loaded into the seat hole, so the interference fit can prevent the phenomenon of going round outside. The change of chemical composition of the inner surface alloy layer can meet the requirements of different bearing pressure, different service temperatures, and different sliding speeds. An oil grooves and oil holes with different structures can meet the requirements of different refueling methods and prevent the phenomenon of the biting shaft.
The bimetallic bearing has the advantages of good wear resistance, especially suitable for medium speed, medium load, and low speed and high load. Various oil slots, oil holes, and oil holes can be machined on the friction surface by special technological means, so as to adapt to the use under different lubrication conditions. The products are mainly used in the balance bridge bushing and gasket of heavy vehicles. Automobile engine, chassis, motorcycle clutch, gear pump wipe plate, and lifting equipment, and other fields.
