KDB 103

KDB 103

  • Material

    Mild steel + porous sintered copper + PTFE/special packing (black)

  • Application features

    A high PV value material specially developed for oil pumps

    Low friction factor and good cavitation and flow corrosion resistance

    Suitable for linear, swing, and rotary motion

    Higher carrying capacity and higher linear speed

    Used in medium and high pressure oil pumps, high-speed oil cylinders, automobile air-conditioning compressors, high-pressure common rail pumps and shock absorbers, etc.
