About the brand
About INA
A Schaeffler brand; Schaeffler built the cage-guided needle roller bearing in 1949.
INA is a product brand of Schaeffler, founded in 1946 in Herzogenaurach, Germany, by Dr. Wilhelm and Dr.-Ing. E.h. Georg Schaeffler. Schaeffler developed the cage-guided needle roller bearing in 1949, patented it in 1950 and registered the INA trademark in 1951.
In 2006 INA-Schaeffler and FAG Kugelfischer merged into Schaeffler KG. Schaeffler's product brands are Schaeffler, INA, FAG and LuK.
Top-performing INA and FAG bearings carry Schaeffler's X-life quality seal, marked XL in the part number: higher basic dynamic load ratings than conventional bearings, so a longer rating life.
