HD250 HD250 HD400-7 HD400GL HD400GS HD400MC HD400SE Bulldozer Top Carrier Roller For Undercarriage Parts

  The carrier sprocket body is meticulously crafted from high-grade materials such as 40Mn2, 40MnB, and 50Mn, which are selectively chosen to er to the diverse demands of various operational settings. The wheel body undergoes a precise sequence of forging and normalization, followed by an advanced spray heating and quenching procedure. This meticulous methodology ensures a tread surface hardness within the HRC52 to HRC62 range, accompanied by a hardened layer depth of 7-10mm (exhibiting a hardness of HRC45) or greater.

   Crafted to endure both tropical and cold climates, the product features high-grade, standard floating oil seals and a dependable lubriion system. This ensures that the carrier sprocket remains fully enclosed and maintenance-free, even in harsh operating conditions or when exposed to extreme temperatures spanning from -45°C to 120°C.
