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.

Abstract: Disclosed is a cast iron material, especially a ledeburite cast iron material which has a high carbide content of at least 15.0 percent by weight and is provided with a characteristic, free, evenly distributed graphite embodiment that can comprise flake graphite and/or vermicular graphite and/or nodular graphite. The basic matrix can be embodied in a pearlitic and/or bainitic and/or martensitic manner according to the application thereof (diameter (D) of the seal of the running gear, peripheral velocity). The thermal conductivity of the inventive material is three to four times greater than that of white cast materials as a result of the high graphite content, thus advantageously preventing seals of running gears from fretting in case of great peripheral velocities (>5 m/s) and large diameters (D>600 mm) of the seals.

Abstract: A weighing system that operates according to the principle of electromagnetic force compensation, having two connecting rods (2, 3) which are fashioned as a parallel guide and connect a load receiver (4) to a base area (1) fixed to the housing, and having an angle lever (5) mounted on the base area. The force due to weight that is transmitted by the load receiver acts upon the short lever arm (5?) of the angle lever via a coupling element, and a coil projecting into the air gap of a permanent magnet system (7) is fastened to the long lever arm (5?). The weighing system occupies only a small area since the long lever arm takes the form of a vertical lever arm and extends, at least in part, in the area underneath the connecting rods of the parallel guide. The permanent magnet system is likewise arranged underneath the connecting rods of the parallel guide.
