ZYB-720 bimetal bearing is a product with steel plate as the base body and CuPb24Sn4 alloy sintered on the surface. The product has good fatigue strength and bearing capacity. It is suitable for occasions with medium speed and medium load and oil lubrication. When the surface is plated with soft alloy, it can be used as a high-speed internal combustion engine bearing and connecting rod bushing to achieve good wear resistance and fatigue resistance.
