Bearings: The Achilles Heel of Wind Turbines – Watts Up

Aug 26, 2014· Changing bearings high in the air on top of a wind turbine tower is not a job for the faint hearted! One of the worst environments for turbines is the use of gas turbines in naval vessels. The large naval marine turbines have to be cogged constantly in harbour, as any chop or pounding will increase the bearing degredation.
