KDB 303

KDB 303

  • Material

    Carbon steel +CuPb24Sn1

  • Application features

    Suitable for oil lubrication, lower friction factor

    It has high fatigue strength, good lubricity, and is susceptible to corrosion by lubricating oil. It is recommended to use soft alloy plating on the surface.

    Oil holes, oil holes or oil tanks can be set

    The sliding layer can be refined to improve the matching accuracy

    Suitable for medium load and medium speed conditions

    Used in high-speed internal combustion engine spindle, connecting rod, gearbox, oil pump side panel, etc.
