NTN Corp. plans by fiscal 2013 to spend JPY 30 to JPY 40 billion (up to USD 521 million) to overhaul domestic production of industrial machinery bearings. The company will first move production of mass-produced items for construction machinery and steel equipment from its plant in Kuwana, Mie Prefecture, to five plants in Ishikawa Prefecture. Those sites will continue to make bearings for wind turbines. In space at the Kuwana plant left vacant by the change, new equipment will be installed for small-volume production of high-precision products such as bearings for aircraft and machine tools and to increase output of replacement bearings. The company announced that a new plant in Shika, Ishikawa Prefecture, will begin heat treatment and other bearing production pre-processes this fall, creating a start-to-finish mass production structure in the Hokuriku region. By restructuring to make production more efficient, the company aims to raise sales of industrial machinery bearings to JPY 144.5 billion in fiscal 2013, a 45% jump from fiscal 2010.
