  • What bearings are used in wind turbines? - Insight -

    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.
