Which of the following types of bearings are used as line shaft bearings?

Correct Answer: Option D — Ring-oiled, Babbitt-faced, spherical seat, shell

Intermediate line shaft bearings traditionally utilize ring-oiled, Babbitt-faced, spherical-seated shells. The spherical seat accommodates minor hull deflection and shaft misalignment, while oil rings continuously deliver lubricant from the reservoir to the journal surface.
