NTN bearings

The beginning of the Japanese bearing industry was started by competitor Nippon Seiko (now known as NSK) producing such bearings in 1914. Four years later in 1918, Nishizono Ironworks, a factory in Uchibori, Mie Prefecture began producing ball bearings.

In the following year, NTN Toyo changed its name to NTN Corporation while creating a new constant-velocity joint factory and research and development center for NTN Driveshaft in Columbus Indiana. .

As a result of giobalization，with bearings being further governed by international guidelines, NTN consolidated its foreign operations while trying to expand further into cutting edge markets. In order to expand North American operations, the company formed NTN USA Corporation, which was slated to become a holding company for their existing US divisions. They also established an office to oversee the fabrication activities of their existing operations. One of NTN's objectives was to begin production of constant-velocity joints in North America. One of their first steps in doing so was the 1996 purchase of Federal-Mogul's ball bearings sector.
