E200B Heat Treatment Excavator Undercarriage Spare Parts High Duty Forged Steel Top Carrier Roller

1. What is Carrier Roller?

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 also 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—making its quality particularly vital. Belt conveyor rollers primarily come in two material options: steel and plastic.

Carrier rollers (used in heavy machinery undercarriages), material selection is tailored to working conditions, with common choices including 40Mn2, 40MnB, and 50Mn. These rollers undergo a rigorous manufacturing process: first precision forging followed by normalization, then overall heat treatment—this sequence 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 on their contact surfaces.

Equipped with high-quality floating seals and a reliable lubricating system, track and carrier rollers adapt seamlessly to diverse climates and temperatures. They operate stably under severe working conditions or extreme temperatures ranging from -45℃ to 120℃, while keeping the components maintenance-free—further enhancing their reliability for heavy-duty applications like mining and construction.

2.Unrivaled Performance and Durability

Crafted from high-strength alloy steel via advanced hot-forging, carrier rollers offer top-tier durability. Built to withstand extreme loads and impacts, they excel in construction/mining—performing reliably even on rocky terrain or compacted soil.

Rigorously precision-designed for flawless track alignment, these rollers cut friction/wear, extending undercarriage life by 40% vs. traditional models. This means fewer replacements, lower maintenance costs, and higher on-site productivity.

Designed with hassle-free upkeep in mind: sealed lubrication (reduces dirt intrusion) and tool-free disassembly cut maintenance time by 30%. Less wear also means longer service intervals, minimizing downtime.
