Thordon SXL 250mm
Thordon Bearings Thordon SXL 250mm is listed as 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. Where an operating value, tolerance, wear limit or setting is not explicitly stated in the source data, refer to the manufacturer documentation for the exact figure.
