Granit Drilled Pin 50x390 mm in Nitrocarburized C45 Steel

Professional high-resistance drilled pin (Code 50915BB5001), manufactured from C45 steel with h9 precision tolerance. This component, equivalent to original reference BB 50 390, is designed for heavy-duty mechanical applications requiring superior protection against wear and oxidation in industrial and agricultural environments.

Nitrocarburization Treatment and Surface Quality

The Granit pin undergoes a ferritic nitrocarburization process, an advanced thermochemical treatment that provides the surface with a distinctive black anti-corrosion finish. Besides effectively protecting the component from external agents and oxidation, this process ensures excellent sliding properties, reducing mechanical friction and preventing galling of articulation points. The h9 dimensional precision guarantees millimetric accuracy, making it essential for machinery subject to very high structural and mechanical loads.
