What is the primary purpose of line shaft bearings?

Line shaft bearings are critical components in marine propulsion systems, specifically in relation to the shaft that transfers power from the engines to the propellers. The primary purpose of these bearings is to support the weight of the shaft as it rotates. This support is vital for ensuring that the shaft remains aligned and operates smoothly without excessive friction or wear, which could lead to mechanical failure.

By providing crucial stability and support, line shaft bearings help to maintain optimal performance in the ship's propulsion system. Proper functioning of these bearings contributes to the overall durability and reliability of the machinery, ultimately ensuring efficient propulsion and operational safety at sea.
