See our water-lubricated, oil-free hydrodynamic bearing seals designed for marine load support and smooth lubrication. These precision engineered seals are ideal for yachts, propulsion systems and stern tube applications, delivering low friction, enhanced wear resistance and long service life in harsh seawater conditions.

With extensive expertise in water-lubricated bearing seal technology, we design and manufacture high-performance Hydrodynamic Bearing Seals that deliver smooth hydrodynamic lubrication, stable load support and long service life for yachts and marine propulsion systems. Our oil-free seals use advanced composite materials and precision groove engineering to minimize friction and wear, reduce maintenance needs, and eliminate grease leakage risk. Backed by strict quality control and ongoing innovation, our solutions provide high reliability, low lifecycle cost and improved environmental compliance for demanding marine applications.

Under the same conditions, Techemer elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means Techemer bearing has longer service life, higher reliability and lower maintenance cost.

Our hydrodynamic bearing seals are extensively used in:
