What is the main function of bearings in a marine propulsion system?

The main function of bearings in a marine propulsion system is to support rotating elements and reduce friction between moving parts. Bearings are essential in preventing sagging or misalignment of the shafts as they rotate, allowing for smooth operation of machinery. By maintaining the correct alignment and providing a stable support structure, bearings help ensure that the components of the propulsion system operate efficiently and effectively.

While bearings may indirectly contribute to other factors such as engine performance or fuel consumption, their primary role centers around stability and friction reduction. This is crucial in a marine environment where the propulsion system endures significant loading and movement. Properly functioning bearings extend the lifespan of machinery and reduce wear on critical components, thereby enhancing overall system reliability.
