Custom Wind Turbine Brush Seals
Flexible strip brush seals for nacelle, tower, hub, and blade-pitch gaps. Drawing-based OEM, replacement, and volume production.
Flexible Brush Seal Applications in Wind Turbines
Flexible brush seals adapt to curved, moving, and variable gaps in wind-turbine assemblies while helping limit dust, moisture, and debris ingress.
- Nacelle-to-Tower / Yaw Interface
Seal the annular gap between the nacelle and tower while allowing yaw movement.
- Hub-to-Blade / Pitch Interface
Follow the circular gap around the blade root and pitch bearing to help block dust, moisture, and debris.
- Hub-to-Nacelle Gap
Seal large curved gaps between the rotating hub and nacelle to help protect internal components.
- Curved & Irregular Nacelle Openings
Flexible profiles can follow round, curved, or angular contours where rigid seals are difficult to fit.
For offshore or coastal installations, moisture, salt exposure, movement, and corrosion requirements should be considered when selecting the brush profile and filament.
FAQ
Where are brush seals used in wind turbines?
Typical locations include nacelle-to-tower gaps, hub and rotor interfaces, blade-pitch areas, and selected curved or circular access openings.
Can you provide UV-resistant or flame-retardant brush materials?
Yes. UV-resistant, weathering-resistant, or flame-retardant filament and backing grades can be reviewed when the required material classification and operating conditions are specified on the drawing.
Can the brush seal follow a curved or circular path?
Yes. Straight, angled, curved, axial, radial, and formed profiles can be produced to the approved drawing and mounting path.
Does a brush seal make a wind-turbine gap fully waterproof?
Not by default. Brush seals provide flexible contact and help reduce dust, moisture, and debris ingress. The complete sealing design, clearance, pressure, drainage, and environmental requirements must be reviewed for the equipment.
