The carrier sprocket body is meticulously crafted from premium-quality materials, including 40Mn2, 40MnB, and 50Mn, which are carefully chosen to meet the varying demands of diverse operational environments. The wheel body undergoes a precise series of forging and normalization processes, followed by an advanced spray heating and quenching treatment. This meticulous process achieves a tread surface hardness within the range of HRC52 to HRC62, accompanied by a hardened layer depth of 7-10mm (featuring 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 external and internal surfaces of the wheel body. It is a key component of the H80 carrier roller for mini excavator undercarriage parts.
Designed to withstand both tropical and cold climates, the product incorporates high-quality, standard floating oil seals and a reliable lubrication system. This guarantees that the carrier sprocket remains fully enclosed and free from maintenance, even in severe operating conditions or under extreme temperatures ranging from -45°C to 120°C.
