NTN Corporation

NTN is a precision machinery components manufacturer founded in 1918 to establish domestic production of bearings, which Japan then depended on imports for. Its main product, the bearing, is used in the rotating parts of virtually all machinery, including Shinkansen trains, aircraft, wind turbines, and machine tools, and holds a top-tier share in Japan. Its constant velocity joints, also known as CV joints or drive shafts, rank among the world's top two. NTN is not an obscure maker of minor parts; it is a global precision-components company that supports all rotating machinery and is directly connected to energy conservation.
