INA company was founded in 1946. In 2003 the companies INA, LuK, FAG initiated Schaeffler Group with more than 66 000 employees and turnover of 8.9 billion Eur in 2007. Nowadays INA numbers over 31000 people and has 39 factories worldwide.

One of the main activities of INA is production of components for timing belt drives, including run-around and tension rollers, as well as semiautomatic and automatic belt tensioners, with hydraulic or mechanical operating principle. Besides, INA produces hydraulic lifters for engine valve mechanism and overrunning alternator pulleys-belt dampers.

The quality and reliability of products as well as ability of INA to meet any demands of its customers allowed the company to become a business partner of almost all European car manufacturers. INA tensioners and valve lifters are likely to be found under the hood of Alfa Romeo, Audi / VW, BMW, Fiat, Ford, Mercedes-Benz, Opel, Peugeot, Renault and other brands.

Being an OEM supplier, INA draws great attention to quality and reliability of products supplied to the assembly lines of car manufacturers and the same quality is fully applied to the products supplied under the same brands to the aftermarket. It goes without saying, that high quality cannot be cheap, but the fact that service life of components and units offered by INA for spare parts is comparable with the longevity of OE parts and calculation of real benefit from using them in repair give reasons to even supporters of austerity while selecting spare parts to consider in favour of INA products.

OE supplies to almost all car manufactures of Europe and the USA.
