The high rotational speeds, small production sizes and in particular in this case, an ideal ratio of possible implementation and outer diameter as well as a high level of vibration resistance are characteristics of cast slip ring assemblies. Cast slip ring assemblies are available as carbon or gold-spring wire models. A high level of integration for small production sizes distinguishes the slip ring assemblies with gold-spring wire brushes. Typical applications are machine tools, stranding machines and wind energy systems.
