Bearings for Wave / Tidal / River Power


marinebearings

The world’s oceans are a vast global resource of non-polluting, endlessly renewable energy and with the ever increasing demand for electrical power, harnessing this force has become a major priority. Many companies and countries have invested heavily in developing systems that will generate power and yet still withstand the harsh underwater environment.

For over 35 years, we’ve been supplying environmentally friendly bearing solutions for thousands of hydro turbine and marine applications across the globe. Our customers include Power Generating Plants as well more than 40 Navies and Coast Guards, cruise ships, tankers, ferries, dredgers and many other types of commercial ships.

Thordon’s non-polluting and maintenance free bearings are available worldwide through our factory trained distributor network that spans more than 100 countries. Our application engineers and global technical support will work with you to deliver innovative bearing solutions.
