SH350 HRC53-57 Cast Bulldozer Upper Roller Top Roller Carrier Roller For Undercarriage Parts KTA0958

    The carrier sprocket body is meticulously crafted from high-quality materials such as 40Mn2, 40MnB, and 50Mn, which are carefully chosen to accommodate the diverse demands of various operational settings. The wheel body undergoes a precisely outlined sequence of forging and normalization, followed by an advanced spray heating and quenching process. This thorough methodology ensures that the tread surface achieves a hardness range of HRC52 to HRC62, with a hardened layer depth of 7-10mm (exhibiting a hardness of HRC45) or greater.

  Engineered to endure both tropical and cold environments, the product features top-notch standard floating oil seals and a dependable lubriion system. This ensures that the carrier sprocket stays fully enclosed and maintenance-free, even when subjected to severe operating conditions or extreme temperatures spanning from -45°C to 120°C.
