Question 530Steam Plants - Assistant Engineer

The correct answer is C) Spherically seated bearings. Spherically seated bearings are the most suitable option to accommodate minor turbine shaft misalignment. This is because the spherical design of the bearing allows for some angular movement and adjustment, which helps to compensate for small variations in shaft alignment. In contrast, other bearing types like ball bearings, roller bearings, or spring bearings are less able to accommodate such minor misalignments without increased wear or stress on the shaft and bearings.
