D6 Bulldozer Undercarriage Spare Parts - D6 High Duty Forged Steel Carrier Roller
What is Carrier Roller?
The carrier roller is a critical component of undercarriages, responsible for supporting both the conveyor belt and the weight of transported materials. Its quality directly impacts the service life of excavators and bulldozers.
For belt conveyors, the roller is equally indispensable. Available in diverse types and large quantities, it bears the load of the conveyor belt and materials while accounting for 35% of a belt conveyor's total cost and generating over 70% of the system's operational resistance.
Our carrier rollers for heavy machinery undercarriages are made from premium materials including 40Mn2, 40MnB, and 50Mn. The manufacturing process includes:
- Precision forging
- Normalization
- Overall heat treatment
This process achieves a surface hardness of HRC52-60 and a hardened layer depth of over 7-10mm (HRC45), ensuring exceptional durability, high impact resistance, and strong surface wear resistance.
Equipped with high-quality floating seals and a reliable lubricating system, our rollers operate stably in temperatures ranging from -45℃ to 120℃, making them maintenance-free and ideal for mining and construction applications.
Unrivaled Performance and Durability
Forged for the Toughest Conditions: Meticulously crafted using high-strength alloy steel and advanced hot-forging techniques, these rollers withstand extreme loads and impacts in challenging construction and mining applications.
