Product Name : Bimetallic bearing ( steel backing+ sinter bronze powder)

LOB Bi-metallic composite bearing material consists of steeling backing with lead bronze or lead-free copper alloy(CuPb10Sn10/CuPb6Sn6Zn3/CuPb24Sn4/CuPb24Sn4/CuPb30/AlSn20Cu)lining,bearing material for oil/grease lubricated applications.The copper alloy forms a continuously frame for thermal conductivity.These bearing structures are with high load capacity and good fatigue property.Higher tolearance can be achieved after re-machined from the customers. Lead-free bronze lining bearing material conforms to the European RoHS Directive

Material Properties:
Allows maintence-free and long-life operation;
Suitable for high static and dynamic loads;
With low and smoothly coefficient of friction and without stick-slip effects;
Suitable for dirty,corrosion,impact load and edge loading;
The base material provided a good shock-absorbing capacity;
Can be used over a large temperature range;
Suitable for reciprocating,rotating and oscillating mobvement with start frequency and difficulty to form oil film occasions;
With low wear rate and long life service.

Special designs and material can be made according to your design.
