KEMEL Water-Lubricated Stern Tube Bearings: Using Their Primary Features

Blog | July 11th, 2023

KEMEL is a leading manufacturer of water-lubricated stern tube bearings that are designed to support the propeller shaft and propeller of a marine vessel. They can operate using water as a lubricant instead of oil or grease, making these bearings more sustainable and eco-friendlier.

The water-lubricated stern tube bearings from KEMEL are known to be reliable and sustainable for marine vessels as they boast components and features that others do not possess. Some of the features of KEMEL water-lubricated stern tube bearings are as follows.

Water-Lubricated Design

KEMEL water-lubricated stern tube bearings operate using water as a lubricant. This eliminates the need for oil or grease, making them more environmentally sustainable and reducing maintenance requirements. Using water as a lubricant also reduces the risk of pollution from oil leaks, which is a significant concern in the marine industry. The water-lubricated design also makes sure the bearings operate quietly, creating a more comfortable environment on the ship.

Advanced Polymer Materials

Another feature of KEMEL water-lubricated stern tube bearings is they are made from reinforced polymer materials. The outer shell of these bearings is made from reinforced plastic formed with glass cloth or cotton cloth, while their sliding face is made from elastomer. These materials have excellent resistance to wear and tear, making the bearings more reliable and durable. They can also resist corrosion and chemicals, which is crucial in marine environments.

Stable Performance

KEMEL water-lubricated stern tube bearings feature outstanding durability and stable performance. Their shaft load is balanced through the high elasticity of rubber. It also has an increased coverage area, preventing concentrated load in the aft end. These bearings can even absorb shaft vibration. So, even at high speeds and prolonged usage, they can effectively operate without experiencing premature wear or damage. This quality makes KEMEL water-lubricated stern tube bearings suitable for large vessels.

Easy Maintenance

KEMEL water-lubricated stern tube bearings are designed for easy installation and maintenance. They can be installed without the need for dry-docking, which saves time and money. Additionally, these bearings require minimal maintenance, which reduces operating costs. The use of water as a lubricant also simplifies maintenance requirements since there is no need for oil changes or grease fittings.

High-Temperature Resistance

These bearings from KEMEL are designed to operate at high temperatures. They are capable of withstanding temperatures up to 80°C, making them suitable for use in vessels that operate in warm climates. The advanced polymer materials used in the bearing’s design and components have excellent heat resistance properties, which ensure the bearings maintain their integrity even at high temperatures.

Design Variations

KEMEL water-lubricated stern tube bearings feature different designs to meet the specific requirements of each application. They can be designed to fit a wide range of shaft sizes and configurations. The use of advanced materials and manufacturing techniques also allows KEMEL to customise the bearing’s design to meet the unique needs of each application.

KEMEL water-lubricated stern tube bearings are designed to provide reliable and efficient operation for marine propulsion systems. They offer high load capacity, corrosion resistance, low noise and vibration, and many more. By choosing water-lubricated bearings, ship operators can reduce their environmental impact and improve the reliability and performance of their propulsion systems.
