What statement is true concerning the ability of a line shaft bearing to adapt to shaft misalignment as the ship's hull flexes?

Question

Accepted Answer

Some line shaft bearings may have only a bottom half bearing shell, which allows for deflection upwards only. Other line shaft bearings may be spherically-seated self-aligning bearings or conventional non-aligning type bearings.

Answer

All line shaft bearings have only a top half bearing shell, which allows for deflection downwards only. As such no provision is made for allowing for deflection in other directions.
