The carrier sprocket body is meticulously crafted from materials such as 40Mn2, 40MnB, and 50Mn, which are specifically selected to cater to the diverse demands of various operational environments. The wheel body undergoes a precise sequence of forging and normalization processes, followed by a heating and quenching treatment utilizing spray techniques. This results in a tread surface hardness ranging between HRC52 and HRC62, accompanied by a hardened layer depth of 7-10mm (featuring a hardness of HRC45) or greater. This optimal combination of hardness and depth guarantees exceptional durability, particularly in terms of resilience against both impact and surface wear, on both the external and internal surfaces of the wheel body.
To accommodate both tropical and cold climates, the product is equipped with high-quality, standard floating oil seals and a dependable lubrication system. This ensures that the carrier sprocket remains fully sealed and requires no maintenance, even in harsh working conditions or under extreme temperatures spanning from -45°C to 120°C.
