fuchs urethyn xhd 2 high performance grease for turbines, tube

Generator bearings differ from all other grease applications throughout a wind turbine. Pitch and main bearing applications focus on low temperature, low speed and high loads, whereas the generator is defined by high speed (up to 18,000 RPM), high temperature (up to 150°C) and fluctuating operating conditions. These different parameters within generator bearings require a grease that is specific to the application and has to mitigate the extreme vibratory wear potential within the wind turbine. Not only does the grease need to be designed for generator bearings, but it should be specifically developed for the unique challenges that a generator faces up tower. Reoccurring temperature faults within the generator caused by lubricant failure and lack of protection of the bearings can result in downtime and the loss of power generation. Bearings can reach temperatures of above 150°C. Most standard industry generator greases are not rated to operate at such high temperatures. 1 tube for sale
