In the wind turbines of today more power is generated in increasingly compact spaces, inevitably resulting in higher loads and higher temperatures. Experience has shown that gear oils that are often in use today are not always able to fully meet the requirements in terms of wear protection in rolling bearings, micropitting resistance or foam and residue formation.

To overcome the weaknesses of existing products, Klüber Lubrication has developed special gear oils that can withstand high loads. Following an extensive series of R&D activities and comprehensive testing, three synthetic high-performance gear oil series are meanwhile available:

• Klübersynth GEM 4 N (polyalphaolefin)

• Klübersynth GH 6 (polyglycol)

• Klübersynth GEM 2 (rapidly biodegradable ester)

Compared with standard oils, these products show better ageing resistance and load resistance, and lower friction. This allows long oil change intervals, less power loss and a considerably higher plant yield – adding up to several thousand Euros over the whole life of the plant. Gear oils made by Klüber Lubrication meet not only the requirements of the gear manufacturers, rolling bearing manufacturers and wind turbine manufacturers, but those of the operators as well.
