Shaft Log

Shaft logs are an important component of marine hardware and hull items in the supply class Marine Hardware And Hull Items in the supply group Ship And Marine Equipment.

A shaft log is a cylindrical housing that supports and guides the propeller shaft in a ship or marine vessel. It is typically made of durable materials such as bronze or stainless steel to withstand the harsh marine environment. The shaft log is designed to provide a watertight seal around the propeller shaft, preventing water from entering the vessel.

The main function of a shaft log is to support the propeller shaft and ensure smooth rotation, reducing friction and wear. It also helps to align the propeller shaft with the engine and propeller, ensuring efficient power transmission.

Shaft logs are available in various sizes and configurations to suit different types of vessels and propulsion systems. They are typically installed in the hull of the ship, near the stern, where the propeller shaft exits the vessel.

In summary, shaft logs are essential marine hardware components that provide support, alignment, and a watertight seal for the propeller shaft in a ship or marine vessel.
