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

2.1 Forged for the Toughest Conditions

Carrier roller are meticulously crafted using high-strength alloy steel and advanced hot-forging techniques, ensuring unparalleled durability and longevity. These Carrier rollers are designed with robustness in mind, capable of withstanding extreme loads and impacts. This makes them the perfect choice for challenging construction and mining applications. No matter the environment, whether navigating through rocky terrain or plowing through dense soil, these Carrier rollers consistently deliver reliable performance in the harshest of conditions.
