Stern Tube Bearing · Shaft Line Equipment
Thordon Bearings Thordon CompacSeries 500mm is a Stern Tube Bearing within the Shaft Line Equipment category. It is typically installed along the propulsion shaft line between the engine or gearbox and propeller, including stern-tube and intermediate support positions. Its engineering role is to support, seal, align or transmit propulsion torque while maintaining controlled shaft motion through the hull. The complete model designation should be retained when matching drawings, certificates, service information and spare parts because neighboring variants may differ in configuration even when they share the same equipment family. The exact shipboard arrangement and interfaces remain installation-specific and should be checked against the vessel’s approved drawings and equipment documentation.
