E200B Heat Treatment Excavator Top Carrier Roller with HRC52-60 Hardness and High Duty Forged Steel Construction

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, accounting for 35% of a belt conveyor's total cost and generating over 70% of the system's operational resistance.
