A micro wind turbine project was in jeopardy of being shut down due to the prohibitive costs of the bearings designed for use. For the project to continue, purchasing and manufacturing costs needed to be significantly 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 savings $361,616 was realized.
