Bearings: The Achilles Heel of Wind Turbines – Watts Up With …

26/8/2014· 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.

Wind Energy - System Seals Inc. - Wind Turbine Seals

A revolutionary wind turbine seal design that redefines rotary seals. System Seals has created a corkscrew-style seal that uses the turning action of a rotary shaft to pump escaping grease back inside the bearing where it belongs. During deflections, when grease naturally migrates towards the seal, the Vortex pumps it back inside.
