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.
