Komatsu PC20 High Duty Forged Steel Excavator Undercarriage Spare Parts Track 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. Available in diverse types and large quantities, it 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.
Material and Manufacturing
Carrier rollers used in heavy machinery undercarriages feature material selection tailored to working conditions, with common choices including 40Mn2, 40MnB, and 50Mn. These rollers undergo a rigorous manufacturing process:
- Precision forging followed by normalization
- Overall heat treatment
- Surface hardness of HRC52-60
- Hardened layer depth of over 7-10mm (HRC45)
