Gamma seals, also known as Axial face seals, are used to protect bearings and conventional radial seals in dirty and demanding applications. They can be
used as a primary seal for grease, oil, and against water splash, dirt, and other contaminants. In addition, these seals can be used as an auxiliary dirt seal to
protect other radial-lip seals. A Gamma seal is made up of an elastomer sealing lip contained in a metal carrier. This design copes with arduous static and
dynamic conditions in mobile hydraulics and power transmission applications. They tend to function on a rotating or stationary shaft, but not an oscillating
one.
