Manufacturer
The brand INA started in 1946 when two brothers Georg and Wilhelm Schaeffler started their company in Herzogenaurach (Germany). A few short years later, Georg Schaeffler invents the cage-guided needle roller bearing, for which a patent was filed in 1950. Since then, the company has become the world leader in making various bearings for various industries.
Since 1971, the INA brand has been a supplier of original parts for various car manufacturers
from Audi, BMW, Mercedes-Benz & Volkswagen. Nowadays this list has grown and INA is also a supplier
from, among others: Alfa Romeo, Ford, Fiat, Seat, Volvo, Opel, Peugeot, Renault, Rover, Saab & Nissan.
In 2003, the company merged with the companies FAG and LuK, after which the name "Schaeffler Group" came into being.
