  • Sterntube bearing problems - Brabon Engineering Services

    A high temperature typically indicates compromise of the hydrodynamic lubricant film over a portion of the bearing. This may be a transient increase in shaft load say during heavy manoeuvring, or low maximum load margin due to poor alignment between bearing and shaft journal, or lubricant condition degradation, e.g. water contamination due to seal leakage.
