FAG Maintenance Products The FAG brand started with an ingenious idea. In 1883, Friedrich Fischer designed a ball grinding machine in Schweinfurt, Germany that, for the first time, made it possible to produce absolutely round steel balls by grinding. This invention is regarded as the foundation for the entire rolling bearing industry. This is one of the reasons why FAG has long been considered to be a pioneer in rolling bearing technology.
