    CuPb30 Layer Bimetal Bushing

    The CuPb30 Layer Bimetal Bushing refers to a bushing made of a bimetallic material consisting of copper (Cu) and lead (Pb) with a Pb content of approximately 30%. This type of bushing has excellent self-lubricating properties due to the presence of lead, which helps reduce friction and wear during operation. Additionally, the copper base provides good strength and conductivity, making it suitable for various applications requiring high wear resistance and electrical conductivity. The CuPb30 layer is typically applied to the inner surface of the bushing, either by casting or other metalworking techniques, to create a wear-resistant and self-lubricating surface.

    bimetal bearing with steel as backing and sintered CuPb30 as lining layer. It has good performance in the anti-seizing shaft and cover-up an alien substance due to the high lead composition. If over plated certain soft alloy on the bushing, it can be used under high speed and middle or low load,e.g.master bearing shell of the internal combustion engine,connect-rod, and rocket arm bushing.

    The bimetal bushings-700 are bimetal sliding bushings with a steel strip and sintered CuPb30 as the surface sliding layer.
    These sliding bushings have good anti-locking protection and a high proportion of lead, meaning that they can bind more dirt particles and impurities, thereby preventing a seize-up.

    Bimetal Bearings 700 Feature


    700 bimetal bearings are based on sheet steel, the surface-sintered CuPb30Material products. The production due to the high lead content, so both good anti-bite axis and foreign objects are buried.
    If the working surface is coated with soft alloy material, it can be used as the main bearing of a high speed, medium and low load internal combustion engine, connecting rod bushing and rocker arm bushing.
