Seventomatic® Flyer

Last update: 24.03.2020

Freudenberg Sealing Technologies has developed the Seventomatic shaft seal for wind turbines, addressing challenges in sealing technology. This innovative seal, inspired by the number 7 and the Latin word 'ventus' for wind, offers superior performance for large, grease-lubricated main bearings. It compensates for large shaft deflection, provides omnidirectional flexibility, and maintains constant lip force, ensuring reliability and leakage-free operation in large wind turbines.
