NTN Corporation was founded in March 1918, which was principally engaged in research, development and manufacture of bearing in the early stage. With evolution, most of NTN's effort has been changed into the manufacture and sales of bearings, Constant Velocity Joints (CVJ) and precision machinery since the Joint-stock reform in 1934. NTN is expanding business scales by supporting all kinds of machinery products which take bearing as the center and are indispensable for industrial development during the last 90 years.
