Gleason Slip Rings
solve a common problem in today’s world: Transfer of electric current from a
stationary to a rotating component. There is a Gleason Slip Ring for virtually
anything that rotates on a fixed axis and requires a flow of electricity.
Electric current is transferred through copper graphite brushes onto copper
alloy rings.
Constant contact is maintained between brushes and rings
through a variety of unique spring designs, depending on unit type, to insure
optimum surface contact and reliable current flow. In some applications the
brushes rotate around the rings (example; rotating signs) while in others the
rings rotate inside the brushes (example; cable reels).
Standard models are available with ratings from 30 to 700 amps at 600 volts in 3 basic styles:
COMPACT for work in small areas with
light and medium duty requirements, ROTAPOWER,
designed for a wide range of applications and HIGH AMPERAGE. Data for all 3 series are shown on the chart below. Most
Gleason Slip Rings are also available in watertight and dust tight enclosures.
In addition, heavy duty models are available for up to 15,000 volt applications.
