The carrier sprocket body is meticulously crafted using premium-grade materials such as 40Mn2, 40MnB, and 50Mn, which are meticulously selected to cater to the diverse operational demands of various environments. The wheel body undergoes a precise series of forging and normalization processes, followed by an advanced spray heating and quenching treatment.
This meticulous manufacturing process results in a tread surface hardness ranging from HRC52 to HRC62, accompanied by a hardened layer depth of 7-10mm (featuring a hardness of HRC45) or greater. This optimal combination of hardness and depth ensures exceptional durability, particularly in terms of resistance to both impact and surface wear on both the exterior and interior surfaces of the wheel body. It serves as a vital component in the H80 carrier roller for mini excavator undercarriage parts.
Engineered to endure both tropical and cold climates, the product features high-quality, standard floating oil seals and a dependable lubrication system. This ensures that the carrier sprocket remains fully enclosed and maintenance-free, even in harsh operating conditions or under extreme temperatures, ranging from -45°C to 120°C
