These components, made out of cast steel with reinforced geometry at stressed sections, undergo accurate machining and induction hardening process specifically tailored to the different sizes.

This allows perfect inter changeability and superior wear resistance.

In both cases, the teeth are subject to an induction hardening process which gives them a surface hardness of Rockwell C 54, with a case depth of 4 to 8 mm depending on size, at Rockwell C 40.
