    Sintered Bronze bushes with good abrasion and corrosion resist bimetal oilless bushing


    Bronze bushing with good abrasion and corrosion resist bimetal sliding bushing


    Specifications:



    Features of Bushing

    Maintenance-free!

    No lubrication required (PTFE composite)

    Minimum wall thickness, minimum space requirements

    Accommodation of heavy loads

    Wide range of temperatures

    Good sliding properties

    High wear resistance


    Description:


    Oilless bearing (bushing) takes steel plate as a substrate and is a kind of wrapped sliding bearing by


    agglutinating spherical bronze powder inside the middle part and rolling the mixture of PTFE (PTEE) and


    lead on the surface. It has the characteristics of small friction coefficient, wear-resisting, corrosion


    resistance and oil-free lubrication. Using this product can reduce costs, reduce mechanical volume, avoid


    bearing seizure phenomenon and reduce mechanical noise. The product has been widely applied in the


    sliding parts of various machinery, such as printing machine, elevator, spinner, tobacco machine, body-


    building, instrument, hydraulic pressure van, micro electrical machinery, solenoid valve, automobile,


    motorcycle and farm & forestry machinery and so on.


    1, Non-oil lubrication or less lubrication


    2, Low maintenance, with better abrasion resistance


    3, Low friction index and anti-aging.


    Roughly introduction:


    Materials


    1. PTFE with mixture 0.01~0.03mm


    2. Porous bronze 0.2~0.3mm


    3. Steel backing 0.7~2.3mm


    4. Tin-plating 0.005mm or copper plating 0.008mm
