In 1939, NTN built Kuwana Works, a global manufacturing center which later became the first Japanese manufacturer to be awarded the Deming Award for statistical quality control.

NTN Bearing Corporation of America was established in Chicago in 1963. At that point in time, NTN was manufacturing ball bearings, spherical, tapered, cylindrical, and needle roller bearings, and automotive constant velocity joints. Later in the 1980s, NTN acquired the Bower™ brand from Federal-Mogul Corporation. Ten years later, NTN acquired BCA™ from Federal-Mogul to complete its product line with automotive clutch release bearings and specialty agricultural bearing assemblies. These growths and acquisitions have made NTN a superpower bearing company.

In 2008, NTN purchased French bearing manufacturer SNR Bearing Company, which was the fifth largest bearing manufacturer in Europe at the time. Through the SNR acquisition, NTN expanded both its position in Aerospace and SNR’s exceptional spherical roller bearing line of products.

2018 marked NTN’s 100th Anniversary. As of now, NTN operates over fifty factories worldwide and is the third largest bearing manufacturer worldwide.
