The carrier sprocket body is meticulously crafted from high-quality materials, including 40Mn2, 40MnB, and 50Mn, which are carefully chosen to meet the diverse operational needs of various environments. The wheel body undergoes a precise series of forging and normalization procedures, followed by an advanced spray heating and quenching process.

    The meticulous manufacturing process achieves a tread surface hardness that falls within the range of HRC52 to HRC62, coupled with a hardened layer depth of 7 to 10 millimeters (exhibiting a hardness of HRC45) or more. This combination of optimal hardness and depth guarantees exceptional durability, especially in terms of withstanding both impact and surface wear on both the external and internal surfaces of the wheel body. It is a crucial component in the H80 carrier roller, specifically designed for mini excavator undercarriage parts.

     Designed to withstand both tropical and cold climates, the product incorporates high-quality, standard floating oil seals and a reliable lubriion system. This guarantees that the carrier sprocket remains fully enclosed and free from maintenance requirements, even in harsh operating environments or when subjected to extreme temperatures, spanning from -45°C to 120°C.
