Wärtsilä Stern Tubes

Oil & water lubricated stern tubes

Wärtsilä stern tube solutions are ready to install stern tubes as standards, but can be custom designed to fit the specific vessel and is assembles to the hull construction by means of resin chocking. The solutions are designed to meet each customer requirement and specification.

Wärtsilä standard stern tube assemblies are fitted with centrifugally cast white metal bearings or composite bearings depending on the application or lubricating medium.

The solution encourages a fit-and-forget concept as bearings and all additional items are already fitted and installed upon delivery.

The installation and alignment is a simple and swift procedure when compared to older traditional methods, allowing for significant reduction in installation time and resources.
