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. Today, FAG is one of the leading brands for applications in machine building, the automotive industry and in aviation and aerospace technology. The Schaeffler Group's FAG brand has companies, subsidiaries and sales agencies in all major industrial countries.

Since 2001, FAG has been part of the Schaeffler Group and has been active in all of the group’s divisions – Aerospace, Automotive and Industrial. Together with INA’s complementary product range, FAG has one of the widest product portfolios in the rolling bearing industry, covering nearly all applications in production machinery, power transmission and rail technology, heavy industry and consumer products.

FAG ball bearings and roller bearings are manufactured as standard and special bearings in many designs and sizes with diameters ranging from 3 millimeters to 4.25 meters. Together with INA, FAG offers customers comprehensive support and services for the diagnosis, maintenance and mounting of rolling bearings and complete systems.

As a forward-looking company, the Schaeffler Group with its brand FAG has invested significant amounts in research and development. Modern simulation methods and testing facilities as well as special materials engineering laboratories ensure the continuous development and improvement of all product lines and confirm the innovative force of FAG.
