Rocker arms and cam followers components should meet not only tribologic specifications but also resistance and rigidity standards. Ductile iron castings can replace forged parts for cost reduction and, if needed, heat and surface treatments can be applied. Rocker arms are casted, semifinished or machined, with bushing and insert when requested. The complex geometrical shape of these components requires a maximum precision during production.

Rocker arms assemblies can be furnished completely assembled with all components. Some advantages of this system:

• Reduction of suppliers to the final customer
• The assembled device is furnished ready for the engine assembly
• Loan (purchase) and assembly cost reduction for the customer
