 The carrier sprocket body is crafted with precision from superior materials, including 40Mn2, 40MnB, and 50Mn, which are thoughtfully selected to meet the varying needs of different operational environments. The wheel body undergoes a meticulously defined process of forging and normalization, followed by an advanced spray heating and quenching treatment. This detailed approach guarantees a tread surface hardness that falls within the range of HRC52 to HRC62, along with a hardened layer depth of 7-10mm (featuring a hardness of HRC45) or more.

  Designed to withstand both tropical and cold climates, the product boasts high-quality standard floating oil seals and a reliable lubriion system. This guarantees that the carrier sprocket remains fully enclosed and free from maintenance, even under harsh operating conditions or in the face of extreme temperatures ranging from -45°C to 120°C.
