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