System Seals has also developed a new wind turbine seal that virtually eliminates leaks – even after the seal becomes worn. Like run-flat tires on a premium car, this self-correcting feature ensures continuous protection to the main bearing, while preventing leaks, fires and contamination.

All told, the improvements reduce maintenance, downtime and the cost of ownership by approximately 50 percent – no matter where in the world a turbine is located. This new technology is used in OEM equipment, MRO, seal upgrades and repower projects.

With a specialty in large-diameter, custom 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 wind turbine bearing and pitch seals in sizes up to 3,000 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.

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.

System Seals has created a comprehensive Vortex wind energy seal information packet that we mail at no cost. The packet contains a self-playing animated video, a capabilities brochure and a physical sample of the Vortex seal. Register now and we’ll get your packet in the mail by the next business day. Thank you for your interest.

Our wind seals include:

• Main bearing seals—with a groundbreaking design that redirects grease back where it belongs
• Gearbox seals
• Yaw pucks/yaw brake pads and Yaw bearing seals
• Pitch bearing seals—featuring completely redesigned bearing groove dimensions for a multi-faceted, higher-performance seal
• Metallic wear sleeves—eliminating the costly need of grinding and hardening shaft surfaces to accept traditional lip seals

A revolutionary wind turbine seal design that redefines rotary seals.

System Seals has created a corkscrew-style seal that uses the turning action of a rotary shaft to pump escaping grease back inside the bearing where it belongs. During deflections, when grease naturally migrates towards the seal, the Vortex pumps it back inside.

The Vortex wind turbine seal was a stroke of genius that caused a global wind turbine manufacturer to retrofit all of its labyrinth seals with the new design. System Seals spent more than a year refining the design and testing prototypes, installation methods and tooling – both in the lab and in the field. System Seals also provided initial installation training and ongoing evaluations to monitor performance.

The design has revolutionized the way turbine manufactures view main bearings.
