The JF-720 bimetallic bearing is a precision-engineered component that features a robust steel plate as its base material, onto which a CuPb24Sn4 alloy layer is sintered. This unique combination of materials endows the bearing with excellent fatigue strength and remarkable load-bearing capacity, making it particularly well-suited for applications involving medium-speed, medium-load, and oil-lubricated sliding conditions.
When the surface of the JF-720 bearing is further enhanced with a plating of soft alloy, its performance characteristics are significantly elevated. This upgrade allows it to function effectively as a high-speed internal combustion engine bearing and connecting rod bushing, where it exhibits superior wear resistance and fatigue resistance, ensuring prolonged service life and reliable operation even under demanding conditions.
