Blade Root Bushings

High quality blade root bushings

The blade root bushing is a critical part of the wind turbine. The bushings carry the full load of the blade throughout the lifetime of the blade.

With constant movement and dynamic stress – and with the next generation blades sized at up to 100 meters in length and more than 20 tons weight – quality and complete control in production is essential.
