Import Caterpillar Bulldozer Track Roller D9n — Buy in Bulk from Supplier in China

The Caterpillar Bulldozer Track Roller D9N is a forged and cast component engineered for heavy-duty earthmoving applications. It is manufactured from high manganese steel, a material selected for its impact resistance and wear durability under extreme loads. The unit is designed to OEM fitment standards for the Caterpillar D9N series, ensuring compatibility with the track assembly and undercarriage geometry of this bulldozer model.

This track roller features a forged body and a heat-treated surface to withstand abrasive soils and high-stress conditions typical in construction and mining environments. Industry standard practice for such components includes a hardness range of 45 to 55 HRC on the wear surface, with typical dimensional tolerances of ±0.5 mm for critical interfaces. The unit is finished in a yellow coat matching Caterpillar OEM colour codes, which aids in visual identification on site.

Primary buyers include contractors in civil engineering, open-pit mining, and large-scale land clearing projects where machine uptime is critical. The component is supplied as a direct replacement part, with packaging designed to prevent damage during transit. Buyers should confirm fitment for their specific D9N configuration, as variations exist between early and late model years.
