Main steam turbine bearings are lined with _______________.
AI Explanation
The correct answer is C) Babbitt.
Main steam turbine bearings are lined with Babbitt, a soft white metal alloy known for its excellent anti-friction and self-lubricating properties. Babbitt provides a smooth, wear-resistant surface that helps reduce friction and wear on the turbine shaft, improving efficiency and reliability.
The other answer choices are incorrect because:
A) Ferrous oxide is not a lining material used for turbine bearings.
B) Cast-iron is not commonly used as a bearing lining material for steam turbines.
D) Steel, while used in other components of the turbine, is not the primary lining material for the bearings.
