FAG Bearings have been synonymous with high quality for over 120 years. 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. The invention is regarded as the foundation for the entire rolling bearing industry. There is many types of bearings, there are only a part on our website, if you need more information, pls contact us.
