About NTN

The NTN Company started when backer, Noboru Niwa, sales company, Tomoe Trading Co., and engineer Jiro Nishizono joined together in designing and manufacturing the first NTN ball bearings, in 1918. Many years later the new head of NTN insisted that manufacturing be located within the same market as it was sold, thus NTN Bearing Corporation of America was created in 1963. Today NTN is proficient in the production of ball bearings, spherical, tapered, cylindrical, needle roller bearings, and automotive constant velocity joints. In fact NTN has the largest share of the global market for axle bearings and is a trusted supplier of OEM (original equipment manufacturer) bearings to many of today’s car manufacturers. NTN’s devotion to high standards has earned the company numerous awards for quality from clients, such as, Caterpillar, Ford Motor Company, Detroit Diesel, Navistar International Corporation, Twin Disc, and Clark-Hurth. Presently, NTN is operating in over 50 facilities globally and is the third largest bearing producer, in the world.
