NTN bearings

NTN bearings 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.

By 1939, NTN had constructed what would become its global manufacturing center, Kuwana Works, and in 1954, NTN became the first Japanese industrial manufacturer to be awarded the prestigious Deming Prize for statistical quality control. NTN bearings continued to grow throughout the 1950s and 1960s as additional factories were built and NTN sales operations expanded to Europe.
