The carrier sprocket body is meticulously crafted using superior materials such as 40Mn2, 40MnB, and 50Mn, which have been meticulously selected to cater to the varying operational demands encountered in diverse environments. The wheel body undergoes a precise sequence of forging and normalization processes, followed by an advanced spray heating and quenching treatment to ensure optimal performance.
The meticulous manufacturing process ensures that the tread surface attains a hardness ranging from HRC52 to HRC62, accompanied by a hardened layer depth of 7 to 10 millimeters (with a hardness of HRC45) or greater. This optimal blend of hardness and depth provides exceptional durability, particularly in resisting both impact and surface wear on both the outer and inner surfaces of the wheel body. It serves as an essential part in the H80 carrier roller, specifically engineered for undercarriage parts of mini excavators.
Engineered for resilience in both tropical and cold climates, the product features high-standard floating oil seals and a dependable lubrication mechanism. This ensures that the carrier sprocket remains fully enclosed and maintenance-free, even in severe operating conditions or when exposed to temperatures ranging from -45°C to 120°C.
