Modern wind energy farms have much higher levels of performance, comfort and reliability than those which were installed in the early days of wind energy. One thing is still true, however, and will remain so: nothing will work efficiently without good lubrication. Whether roller bearings, gearings, gaskets or hydraulic cylinders, everything has to be cooled, protected and lubricated for it to operate efficiently and to be able to attain its calculated life-span.

A good knowledge of gear technology and tribology are crucial for the correct and comprehensive assessment of a drive mechanism. It is therefore wise to carry out an analysis of the damage or imminent damage. However, action should be taken before any costly damage occurs. So make use of the long experience of Hubert Gregorius with gear and lubricant manufacturers, their many contacts to roller bearing and filter producers, the knowledge they have gained from many working groups in research and science and of course their practical experience gained in the field.
