High current carbon brushes
suitable for mounting in linear adjustable telescopic holders

Special material qualities are required to ensure the lowest possible loss of current transmission. The standard qualities we use
are produced as a plate in a special pressing process and then
machined. They can be supplied in both leaded and lead-free
quality. Both versions are characterized by a high metal content
and consequently high possible current densities of up to 40 A/
cm² resp. 28 A/cm².

When using current transmission systems with telescopic holders, the high-current carbon brushes are suspended in a free
moving manner and can therefore adapt well to the current roller,
slip ring or contact strip. The contact pressure is transmitted by
a pressure spring in the holder.
The design of the carbon brushes is either with or without
radius adapted to the intended use and supplied according
to customer requirements. The telescopic holders can be
mounted in a space saving way and offer a wide range of
options. If possible, the telescope holders should be attached
via an insulated bracket. The current should only be conducted
via the stranded cables to avoid erosion in the holders.
The diameter of the mounting hole for all listed holders
is 22 mm. By means of the two nuts supplied, the current
transmission system can then be linearly adjusted to the
appropriate position and installed.
Telescopic holders with either 50 N or 100 N spring forces
are available. As contact pressure for the high-current carbon
brushes we recommend a value of 2,5-4 N/cm² running surface.
