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.<\/p>\n<h3>Key Features and Benefits:<\/h3>\n<ul>\n<li><strong>Waterproof Seal:<\/strong> Effectively prevents outside water from entering the engine room along the rotating propeller shaft, ensuring the safety and performance of your engine remain optimal.<\/li>\n<li><strong>Axial Operating Principle:<\/strong> 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.<\/li>\n<li><strong>No Shaft Wear:<\/strong> Unlike traditional packing seals, the seal does not clamp directly on the propeller shaft, preventing wear or &#8220;scoring&#8221; on the shaft itself, thus extending the life of your propeller shaft.<\/li>\n<li><strong>Long Lifespan:<\/strong> Thanks to the low friction resistance, this seal lasts much longer than conventional sealing systems, leading to less maintenance and lower replacement costs.<\/li>\n<li><strong>Easy Maintenance:<\/strong> The seal&#8217;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.<\/li>\n<\/ul>\n<h3>Technical Specifications:<\/h3>\n<ul>\n<li><strong>Lubrication:<\/strong> Water-lubricated<\/li>\n<li><strong>Shaft Diameter:<\/strong> 30 mm<\/li>\n<li><strong>Housing Diameter:<\/strong> 56 mm<\/li>\n<\/ul>\n<h3>Installation and Use:<\/h3>\n<p>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).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This <strong>water-lubricated shaft seal<\/strong> provides an advanced, waterproof seal for propeller shaft installations on boats.
