Cooling of the Oil Used in the Guide and Thrust Bearings of Turbine and Generator

Purpose of Guide & Thrust Bearing Oil Coolers
These coolers ensure:

Temperature Control – Prevent overheating of bearing oil, which could lead to:

Reduced oil viscosity → Poor lubrication → Bearing wear/failure.

Thermal expansion → Misalignment → Damage to turbine/generator shafts.

Protection of Thrust Bearings – Thrust bearings handle axial loads from propeller/turbine forces; cooling prevents thermal distortion & failure.

Stable Generator Operation – Overheated generator bearings can cause vibration, insulation breakdown, or even rotor seizure.
