The rotor shaft is the central and simultaneously the highest stressed component in wind turbine engineering. The rotor bearing in particular is permanently subject to high mechanical as well as climatic loads. At stormy wind magnitudes of eight or higher, rotor bearings are subject to high dynamic loads as well as vibrations. In combination with climate impacts such as temperature, snow, ice or rain they can cause premature bearing failure. Lubrication has a high effect on reliability and service life of rotor bearings. LUBCON offers a selection of media-resistant and efficient bearing greases for rotor shaft bearings in wind turbines. LUBCON lubrication solutions have been developed with major bearing manufacturers and extensively tested with wind park operators featuring maximum performance. Markedly lower lubricant consumption and reduced operating, maintenance and repair costs are only a few benefits that come with the use of LUBCON lubricants. To disencumber maintenance staff and to extend maintenance intervals LUBCON offers the central lubrication system EasyMatic HD, a robust and reliable solution for the automatic rotor bearing lubrication. The lubrication system supplies shaft bearings continuously with the right and fresh lubricant amount.
