The bimetal bushing, featuring a steel backing and CuPb24Sn4 alloy lining, offers exceptional wear resistance and durability. The steel backing provides a solid foundation for the bushing, ensuring structural integrity and stability. Meanwhile, the CuPb24Sn4 alloy lining exhibits excellent bearing properties, including high load-bearing capacity, good self-lubricating characteristics, and resistance to corrosion and wear.
The CuPb24Sn4 alloy is a special type of copper-based alloy, containing 24% lead (Pb) and 4% tin (Sn). The addition of these elements enhances the alloy's mechanical properties, making it suitable for applications where heavy loads, high temperatures, and abrasive environments are present.
The combination of steel and CuPb24Sn4 alloy in this bimetal bushing ensures optimal performance in demanding industrial applications. The steel backing guarantees durability and stability, while the alloy lining provides superior wear resistance and self-lubricating properties. This makes the bushing suitable for a wide range of applications, including connecting rods, crankshafts, and other mechanical components.
Bimetal bushing with steel as backing and sintered CuPb24Sn24 as lining layer.
This type has fairly good performance in anti-fatigue and load capacity.
It is suitable for middle speed and middle load.
When over plated certain soft alloy, it can be applied in high-speed internal combustion engine and as connect rod.
bimetallic bearings with steel-backed CuPb24Sn4 alloy are ideal for applications with high load Bearing forms made to order: cylindrical bushes groove type and thrust washers.

Steel shell backed with a lead bronze lining bearing material for oil lubricated applications. This material has high load capacity and good fatigue properties. It is widely used in automotive applications such as compressors, steering gear, power steering, pedal bearings, king-pin bushes, tailgate pivots, mechanical handling and lifting equipment, hydraulic motors, agricultural machinery etc.
Bearing forms available in standard dimensions
Bimetal Bearing forms made to order: cylindrical bushes and thrust washers with non-standard dimensions, sliding plates, customized bearing designs
bimetal bushing is a bimetal bearing with steel back and sintered CuPb24Sn4 as lining. This type has fairly good performance in anti-fatigue and heavy load capacity. It is suitable for middle-speed and middle load. When the soft alloy is plated on the bushing surface and with oil lubrication,it can be applied in a high-speed internal combustion engine and connect-rod.
