Abstract: A cast iron material, particularly a ledeburitic cast iron material with a carbide content of at least 15 wt. % and a characteristic free, evenly distributed graphite formation is disclosed. In this case, the evenly distributed graphite formation may comprise graphite flakes and/or vermicular graphite and/or nodular graphite. Depending on the respective application (diameter (D) of the running gear seal, peripheral speed), the basic matrix may be realized in pearlitic and/or bainitic and/or martensitic form. Due to the high graphite content, the material has a thermal conductivity that is three to four times greater than that of white cast iron materials, wherein this provides the advantage that no scoring of the running gear seals occurs at high peripheral speeds (>5 m/s) and large diametrical dimensions of the seals (D >600 mm). In addition, the high carbide content of at least 15 wt.
