EX60 HRC53-57 50mn Technique Mini Excavator Bulldozer Top Carrier Roller For Undercarriage Parts9062403

  The carrier sprocket body is carefully crafted from top-notch materials, including 40Mn2, 40MnB, and 50Mn, which have been thoughtfully chosen to meet the diverse operational requirements encountered in various environments. The wheel body undergoes a meticulously planned series of forging and normalization procedures, followed by an advanced spray heating and quenching process to guarantee peak performance.

    The precise manufacturing process guarantees that the tread surface achieves a hardness level between HRC52 and HRC62, coupled with a hardened layer that extends from 7 to 10 millimeters deep (possessing a hardness of HRC45 or higher). This combination of hardness and depth offers remarkable durability, especially when it comes to withstanding both impact and surface wear on both external and internal surfaces of the wheel body. It is a vital component in the H80 carrier roller, specifically designed for the undercarriage parts of mini excavators.

     Designed to withstand both tropical and cold climates, the product incorporates high-quality floating oil seals and a reliable lubrication system. This guarantees that the carrier sprocket remains fully enclosed and free from maintenance, even under harsh operating conditions or when subjected to extreme temperatures from -45°C to 120°C.
