NTN began in 1918 when investor Noboru Niwa, his sales company Tomoe Trading Co., and engineer Jiro Nishizono joined together to design and manufacture the first NTN ball bearings. 

Throughout NTN’s more than 90 years serving the industry, NTN have continued to grow product offerings to better serve customers.

In 1954, NTN was the first bearing manufacturer to be awarded the Deming Prize.
