Stern Tube Bearing · Shaft Line Equipment
In a typical shipboard setting, the Kamome Propeller KP Stern Tube System is used on vessels where efficient and reliable shaft alignment is crucial. This complete system includes bearings, seals, and an oil lubrication setup designed to handle shaft diameters from 150 to 700 millimeters. The system ensures smooth operation and minimal wear through a combination of white metal bearings, lip seals, and gravity-fed oil tanks. Regular maintenance routines such as daily checks of the stern tube oil level, quarterly oil analysis, and periodic bearing clearance assessments at drydocks are essential for optimal performance. Common issues include alignment problems leading to white metal wiping, seal wear resulting in oil loss, and drops in oil tank levels from seal leaks. Spare parts can be sourced from Kamome Propeller's Aioi, Japan facility, with a typical lead time of 3-5 weeks for delivery within Asia.
