What is the purpose of the main thrust bearing in a ship?

The main thrust bearing serves a critical function by transferring the thrust generated by the shaft and screw to the hull of the ship. This is essential for the proper propulsion of the vessel. When the engine drives the propeller, significant forces are created that need to be effectively managed and directed through the vessel's structure. The thrust bearing accomplishes this by providing a stable connection point that absorbs these forces, allowing the ship to move efficiently through the water.

Without a properly functioning thrust bearing, the energy produced by the engine could not be effectively converted into forward motion, leading to potential mechanical failures or inefficiencies in propulsion. Thus, understanding the role of the thrust bearing is fundamental for ensuring the reliability and performance of a ship's propulsion system.
