Thanks to a ball mill designed in 1883, Friedrich Fischer is able to volume-produce steel balls with high precision in his Schweinfurt factory, which is seen as its start of the rolling bearing industry. And soon after that, its products have gained success worldwide. Committing to producing continued quality, FAG bearings has won itself a wonderful reputation of quality, which contributes to its acquisition by INA Holding Schaeffler KG in 2001. At present, it still acts as an important part of the Schaeffler Group. FAG bearings could be used in aerospace arena and wind turbines.
