The major goal of adding oil seals to the stern tube (also known as the tail tube) is to ensure the ship's stern and water tightness. Specifically, the oil seals in the stern tube serve the following critical functions:


Prevent water penetration: The stern tube is typically located below the water's surface and comes into touch with water for an extended period. The oil seal keeps water out of the shaft tube, protects the bearings and mechanical parts from moisture, and prevents corrosion and wear on the equipment.


Keep lubricated: The bearings and other rotating parts in the stern tube require lubricating oil to reduce friction and heat generation. The custom oil seals helps to keep the lubricating oil in the system, prevent the lubricating oil from leaking or contaminating, and ensure the normal operation of the equipment.


Prevent dirt from entering: The oil seal can also keep exterior dirt, salt, silt, and other impurities out of the stern tube, preventing mechanical parts from being damaged, particularly in seawater situations where external pollutants can accelerate corrosion and equipment wear.


Extend the service life of the equipment: By preventing water, dirt and lubricating oil from leaking, the oil seal effectively reduces the wear of various components in the stern tube, thereby extending the service life of the entire set of equipment.
