- Post-weld machining in a large 3-axis vertical mill ensures precise geometry and circularity within 10 microns
- Hand-finished weld surfaces reveal any defects, while threaded M50 x 1.5 hubs accept replaceable phosphor bronze bushes
- Zinc flame-sprayed external surfaces and cavity-waxed internal bores provide long-term corrosion protection
- Warranty: 12 months return to factory for supply only, 5 years return to factory if fitted by DC21
Description
New hub arms developed by DC21 in collaboration with Serenity Wind provide a robust replacement for original Endurance components prone to fatigue and wear. Careful material selection, advanced multi-pass welding, and precise post-weld machining ensure superior structural integrity and long-term durability.
Extensive UKAS laboratory testing confirms welds outperform OEM standards, while hand-finished surfaces and threaded, replaceable bronze bushes reduce wear and enable easier maintenance. Enhanced corrosion protection and precise machining improve reliability, operational life, and serviceability, making these hub arms a stronger, safer, and more durable solution for Endurance wind turbines.
