Granit Drilled Pin 90x700 mm in Nitrocarburized C45 Steel

Professional drilled pin for ultra-heavy-duty applications (Code 50915BB9001), manufactured from C45 steel with h9 precision tolerance. This component, equivalent to original reference BB 90 700, is engineered for primary articulation systems in large-scale machinery requiring high structural stability and maximum wear resistance.

Nitrocarburization Treatment and Mechanical Performance

The 90 mm Granit pin undergoes ferritic nitrocarburization, a thermochemical treatment that creates a high-hardness, anti-corrosion black surface layer. This technology drastically improves the pin's sliding properties, reducing radial friction and preventing galling under extreme loads. The C45 steel core provides the necessary toughness to absorb shocks and bending stresses, while the h9 tolerance ensures a micrometric fit, ideal for large earthmoving, heavy agricultural, and industrial sectors.
