Railway tribology

HEF puts its railway tribology experience to work for the rail industry. 

In the railway sector, inspection of components such as doors or even the brakes, benefits from the advantages offered by liquid nitrocarburizing. As a matter of fact, HEF’s CLIN™ technology is acknowledged as a viable and ecological solution that offers a nitriding layer with high-performance tribological properties, excellent microporosity and corrosion resistance by means of traditional methods such as gas nitriding and plasma nitriding. 

On the other hand, HEF designs and manufactures friction components for the world’s top players in the railway industry. 

Our friction components are used in the railway communication control devices, the coupling systems on trains and subways, brake guidewires, signal lights, pantographs, and the equipment for placing and maintaining tracks, etc.
