CWS split water lubricated forward sterntube seal
General
The CWS forward seal has been designed to provide
inboard sealing of propeller shafts with water lubricated
bearings. It can be used for all sea and river going vessels
foreitherclosed oropen lubrication systems.
Execution
The design allows significant radial shaft displacement
caused by wear in the bearing. The static inflatable
secondary seal "pnemostop" allows inspection and repair
of the seal with the vessel afloat or with water in the
sterntube.
CWS is equipped with a split wear insert that makes repair
possible without shaft removal. The housing could as option
be supplied in a split version. The split housing version
minimizes the required free length in front of the seal from
about one extra seal length to just a few centimetres longer
than the seal itself.
The choice of materials makes the seal fully corrosion
resistant provided that the cathodic protection of ship hull
and shaft earthing is made professionally.
