Main propulsion unit, to vary greatly, rotating or reciprocating elements, free axial or radial movement, in a plane perpendicular to the axis of the shaft, free endwise movement, to maintain radial and axial alignment, to be steel backed and white-metal lined, adjustable housings, to allow alignment changes, to be spherically seated, double-tilting pad type bearing, to maintain the correct alignment at all conditions, the loose-fitting lock pins, the thrust collar, the individually pivoted segments, little or no pressure drop, to ensure proper clearance, to be subjected to very severe service.

Read the following definitions and find the corresponding terms which they explain. Match the figure and the letter and insert your answer into the table below. The first has been done for you.

1. A machine part which supports shafts and spindles is called …. 2. The bearings, which serve to maintain the correct radial clearance between the rotor and the casing, are called …. 3. The bearings which serve to limit the axial, that is longitudinal movement of the rotor are called …. 4. The rotating bearing element or … is attached to and turns with the main shaft. 5. A type of bearing using rolling motion to support a load and reduce friction is called …, it produces less friction than plain bearings. 6. A metal alloy often used to line plain bearings, commonly made of large amounts of tin with a smaller amount of antimony, copper, and lead. 7. A type of anti-friction bearing designed with metal balls that provide rolling motion and reduce friction between moving parts. 8. The most common and basic type of roller bearing designed with cylinders of slightly greater length than width. 9. A type of roller-element bearing consisting of a double-row of rolling elements. 10. A type of plain thrust bearing capable of high thrust capacity able to operate even when there is some significant misalignment. 11. The overall force that is applied to a material or structure. 12. A type of roller-element bearing consisting of a single row of rolling elements.								A. Anti-friction bearing B. Axial or thrust bearing C. Babbitt D. Ball bearings E. Bearing F. Collar G.
