System Seals’ Wind-Fit Technology


With a specialty in large-diameter, customized seals, System Seals quickly became a natural fit for the wind industry several years ago during the surge of new turbines. Today, the company produces the industry’s top performing bearing and pitch seals in sizes up to 3000 millimeters in diameter.

Systems Seals engineers have a unique ability to custom design seals in PTFE compound and polyurethane that substantially outperform standard parts. They offer lower friction, greater reliability and are more resistant to extrusion. These advanced designs became known as Wind-Fit Technology, which now leads the wind industry in performance and reliability.

The time and cost involved in replacing turbine seals are far too valuable to rely on standard parts. Talk to a System Seals engineer today to learn how seals designed specifically for each application can be developed and delivered more quickly than most off-the-shelf solutions.
