Oil Lubrication Stern Shaft Seal

Marine Oil-lubricated seals are used most often for sealing rotary shaft applications. Oil-lubricated systems are the most common, but ship owners occasionally use water-lubricated and grease-lubricated systems.

How Oil Lubrication Stern Shaft Seal Work

The oil-lubricated Supreme seals close the gap between stationary and moving components of rotating shafts. It prevents the escape of lubricants (oil leakage) and the ingress of harmful materials such as dirt or sand. The lube oil system circulates the oil and controls pressure, flow and temperature in order to build up an appropriate lubrication film for the white metal slide bearing.
