Nn Inc
A maker of high-precision metal and plastic components, NN Inc. supplies the ball bearings, connectors, and power components that quietly show up in cars, medical devices, electrical grids, and data centers. It was founded in 1980 by Dick Ennen and a team of managers from Hoover Precision Products, starting out as NN Ball & Roller to serve the bearings industry. The name "NN" is simply a phonetic nod to the founder's surname, Ennen.
