NTN Corporation is one of the most prominent manufacturers of bearings in Japan, second domestically only to NSK Limited. The company is one of the largest exporters worldwide of friction-reducing products such as constant-velocity joints. The beginning of the Japanese bearing industry started by competitor Nippon Seiko producing such bearings in 1914. Four years later in 1918, Nishizono Ironworks, a factory in Uchibori, Mie Prefecture, Japan began producing ball bearings.
From 2007-2009, NTN Corporation entered the large component market by establishing NTN Hakui Corporation in Ishikawa. This facility specialized in turning large bearings, while Nanjing Puzhen NTN Railway Bearing Company was formed for the fabrication of railway bearings. Soon after, in conjunction with Korea Flange Co., Ltd. KOFCO Group added Seohan-NTN Driveshaft USA Corporation to its United States conglomerate. In addition to these ventures, NTN HoudatsuShimizu Corporation was set up to manufacture super-large machinery parts and bearings, NTN Transmissions Europe Crézancy was established by the acquisition of Setfoge’s Crézancy facility by NTN Transmissions Europe and NTN Shika Corporation was put in place to forge large bearings. Additionally, at the end of this period, NTN’s Elemental Technology R&D Center was formed in Kuwana.
After then, NTN entered the wind energy market via the establishment of Seohan-NTN Bearing Company. This was a joint-venture with Seohan in South Korea. Additionally, NTN Driveshaft do Brasil and NTN Noto Corporation were formed for constant velocity joints and industrial machinery bearings. Most recently, however, NTN partnered with Luoyang LYC to distribute bearings in China, with mass production in the country expected to begin in 2012.
