A micro wind turbine project was in danger of being shut down due to the prohibitive costs of the bearings being used. For the project to continue, purchasing and manufacturing costs needed to be reduced. NSK engineers identified several areas in the machine design which required modification, to ensure the optimum and most cost effective bearing arrangement was used. By reviewing the complete unit build, a saving of €337.600 was made.
