What is the main purpose of strut bearings?

The main purpose of strut bearings is to support the end of the shaft. Strut bearings play a crucial role in the functioning of marine systems, particularly in propulsion and shaft alignment. They provide necessary support to the shaft, which helps maintain alignment and reduces vibration, thereby ensuring smooth operation. Proper support helps in distributing the loads exerted on the shaft and preventing premature wear.

Other functions, like lubrication or cooling, are typically managed by different components within the system. While the bearings may benefit from lubrication, it is not their primary role; thus, choices related to lubrication and cooling do not accurately reflect the main purpose of strut bearings. Similarly, anchoring functions pertain to different structural components of a vessel, further distinguishing their roles from that of strut bearings.
