Komatsu PC20 Bullozer Undercarriage Spare Parts High Duty Forged Steel 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


Forged for the Toughest Conditions

Crafted with meticulous precision, carrier rollers use high-strength alloy steel and advanced hot-forging techniques—delivering unparalleled durability, longevity, and impact resilience. Engineered for robustness, they withstand extreme loads and harsh impacts, making them ideal for demanding construction and mining applications. Whether navigating rocky terrain, plowing through compacted dense soil, or enduring heavy-duty operation, these rollers consistently maintain reliable performance even in the harshest environments.

Precision Engineering for Optimal Functionality

Carrier rollers undergo a rigorous precision design process, with a focus on optimizing structure to ensure flawless track alignment. This innovative design drastically reduces friction and wear, extending the lifespan of undercarriage components by up to 40% compared to conventional standard models. The practical benefits are clear: fewer replacements are needed, maintenance costs are significantly lowered, and productivity at your worksite is substantially enhanced.

User-Friendly Maintenance

Beyond performance, carrier rollers are engineered with user-centric maintenance in mind. Features like tool-free access to key components and sealed lubrication systems eliminate complex disassembly steps, cutting maintenance time by 30%. Additionally, the reduced wear (from precision design) means fewer servicing intervals—minimizing downtime and allowing your equipment to stay operational longer. This combination of “low-effort maintenance” and long-lasting performance further drives down total ownership costs.
