What type of grease is most commonly used aboard ships?

Lithium-based grease is the most commonly used type of grease aboard ships due to its excellent properties that make it suitable for marine environments. It has a high dropping point, which means it remains stable at elevated temperatures, ensuring it does not break down or lose its lubricating qualities under the heat generated by machinery and engine operations.

Furthermore, lithium-based greases have good water resistance, making them ideal for use in environments where exposure to moisture is a concern, such as on ships. They also provide good mechanical stability, which means they maintain their consistency and performance even when subjected to physical stress and vibration common in maritime operations.

The versatility of lithium-based greases allows them to be used for a variety of applications on ships, from lubricating bearings and gears to serving as grease for winches and other deck equipment. This widespread applicability reinforces its status as the preferred choice for marine lubrication.
