Shaft seal water-lubricated – 45 mm shaft, 75 mm housing

Description

Water-Lubricated Shaft Seal

This water-lubricated shaft seal is an advanced solution for propeller shaft installations on boats, designed to effectively seal the engine room against the intrusion of water. The system operates on an axial principle, providing a reliable and low-maintenance seal. Thanks to high-quality materials, this seal delivers excellent performance even in demanding maritime environments.

Key Features and Benefits:

• Waterproof Seal: Effectively prevents outside water from entering the engine room along the rotating propeller shaft, ensuring the safety and performance of your engine remain optimal.
• Axial Operating Principle: The seal operates along the length of the shaft. This system uses a polished stainless steel glide ring that rotates against a fixed counterface, usually made of graphite or composite, providing minimal friction and reduced wear.
• No Shaft Wear: Unlike traditional packing seals, the seal does not clamp directly on the propeller shaft, preventing wear or “scoring” on the shaft itself, thus extending the life of your propeller shaft.
• Long Lifespan: Thanks to the low friction resistance, this seal lasts much longer than conventional sealing systems, leading to less maintenance and lower replacement costs.
• Easy Maintenance: The seal’s design allows for easy installation. The flexible rubber bellows absorb vibrations and small movements from the engine, stabilizing the operation of the seal and prolonging its lifespan.

Technical Specifications:

• Lubrication: Water-lubricated
• Shaft Diameter: 45 mm
• Housing Diameter: 75 mm

Installation and Use:

For optimal operation, it is recommended to install the seal as close as possible to the forward bearing of the propeller shaft housing. Pay attention to the correct pre-tensioning of the rubber bellows during installation, ensuring the seal continues to function effectively under pressure (caused by the propulsion force of the propeller).
