1. lead-free self-lubricating bearing, it mainly is made up of metal substrate, the spherical porous copper powder layer and the anti-friction wear-resistant plastic layer of infiltration and covering copper bisque that are sintered in above the substrate, and adopts rolling technology, manufactures sliding bearing;

  • It is characterized in that in the said spherical bronze powder not leaded in not leaded and the friction layer plastic formula;

    The polymer material that said anti-friction wear-resistant plastic layer is the bearing bush nexine is formed;

    Be polyphenylene sulfide superfine powder 10~

    20%, polyphenyl fat superfine powder 10~

    20%, aramid fibre 10~

    20% by weight;

    Length of staple is 40~

    120 μ


    Molybdenum disulfide superfine powder 6~

    10%, all the other are the superfine powder of polytetrafluoroethylene body;

    The spring tape of described metal substrate for adopting high-quality low carbon steel to process, the width of spring tape is 150~

    300mm, and thickness is 0.25~

    2.70mm, and carries out copper facing on its surface, and thickness of coated copper layer is at 4~

    6 μ


    The spherical copper powder trade mark of sintering on metal substrate elected C as US n8P or C US n10.
