The carrier sprocket body is meticulously crafted from premium materials including 40Mn2, 40MnB, and 50Mn, which are thoughtfully chosen to meet the diverse needs of various operational environments. The wheel body undergoes a precise series of forging and normalization processes, followed by a heating and quenching treatment employing advanced spray techniques. This results in a tread surface hardness that ranges from HRC52 to HRC62, accompanied by a hardened layer depth of 7-10mm (with a hardness of HRC45) or more. This optimal blend of hardness and depth ensures exceptional durability, particularly in terms of resistance to both impact and surface wear, on both the outer and inner surfaces of the wheel body.
To adapt to both tropical and cold climates, the product is equipped with high-quality, standard floating oil seals and a reliable lubrication system. This ensures that the carrier sprocket remains fully sealed and maintenance-free, even in harsh working conditions or under extreme temperatures ranging from -45°C to 120°C.
