FAG, which is an acronym of "Fischer's Automatische Gusstahlkugelfabrik" or "Fischer's Automatic Steel Ball Factory." The brand stands for the development and manufacture of high-quality rolling bearings, linear guidance systems, plain bearings, and engine components for mechanical engineering, automotive and the aerospace industry worldwide. In 1883 Friedrich Fischer designed a ball mill that allowed machines to produce high precision steel balls. This is seen by many, as the beginning of the rolling bearing industry. Since then, they have been a world renown manufacturer in the ball bearing industry, continuing to develop cutting edge bearing technology.
FAG was bought by The Schaeffler Group in 2001, completing out its portfolio of ball bearing brands. The applications for FAG bearings range from aerospace applications to larger size bearings used for wind turbines. FAG bearings are used in airplanes railway cars, automobiles, and industrial machinery. They have manufacturing facilities in Europe, Asia, Brazil, the US, and Canada.
