    Wieland-GA9

    Wieland-GA9 is a very soft material with the best emergency running properties. Use in case of insufficient lubrication. Well suited for water lubrication. However, the load capacity is not high; therefore mainly used in hydrodynamic applications.
    Application: Underwater pumps.
