Wind Turbine Seals & Accumulators
Sealing Solutions for Energy Generation
The world is heating up and demand for renewable energy is escalating. The result: Sources of power are no longer centralized and energy systems must evolve to handle new operational challenges.
Wind power is an example. By installing new, stronger wind turbines in existing locations, companies can produce more megawatts of sustainable power. Offshore as well, wind energy is increasing as more powerful, efficient wind turbines are erected. The reliability of these remarkable giants depends on components that continuously function in extreme environmental conditions. Freudenberg’s sealing solutions are custom-engineered to address unique system requirements. Founded on the company’s unrivaled material and product expertise, to wind operators around the world.

Sealing Solutions for Wind Power
High-quality and dependable seals for wind energy.
In addition to decades of experience, Freudenberg‘s engineers make use of the enormous material expertise of their globally active company. The development of the new radial shaft seal Seventomatic for the wind industry combines new and proven elements with the precision of today‘s manufacturing processes.
In order to further improve the technical availability of wind turbines, we have developed a new generation of materials: Ventoguard®.
Radiamatic R35 and R55
Radiamatic R35 and Radiamatic R55 radial shaft seals help ensure long-term, reliable performance of the main bearing in wind turbines. The main bearing in a wind turbine is a key component in the generation of electricity from this renewable energy source. For a zero-defect performance the bearing seal has to fulfill the highest requirements.
Merkel Enviromatic EA
Merkel Enviromatic EA is a deflector seal made of elastomeric material featuring an axially acting sturdy sealing lip with a well-defined sealing edge.
Hydraulic Piston Accumulator
The Freudenberg Hydraulic Piston Accumulator consists of two components: a gas chamber and a fluid chamber, with a gas-proof piston seal separating the components.
Diaphragm Accumulators by Freudenberg Sealing Technologies are designed for industrial and mobile equipment applications that demand lightweight, high-strength performance.
Seal for Monopile / Transition Piece - Flange
To meet the new challenges in the Offshore market, FST has developed a more robust seal in terms of seal interference and contact surface.
Seventomatic S71 S73
Seventomatic is an elastomeric shaft seal with an integrated meander spring, offering a flat spring characteristic to ensure a permanent, even preload of the sealing lip.
