Valve trains The large mechanical forces to be transferred impose an immense load on the tappets and are responsible for about 20% of the entire engine friction.

Oerlikon Balzers carbon coatings reduce the friction across the full speed range. The service life and operational reliability of the tappets are significantly increased while fuel consumption is reduced.

In motor sports, it has become standard practice to coat cam followers, tappets, camshafts and valves with BALINIT®.
