Komatsu PC20-7 Undercarriage Rollers Replacement - OEM Top & Carrier Rollers for Mini Excavator | Heavy Duty Factory Direct Parts
1. What is a roller?
In belt conveyor systems, rollers aren’t just parts—they’re the linchpin. With endless types and quantities to match diverse needs, their primary function is non-negotiable: supporting the conveyor belt and bearing the weight of materials in transit. But here’s what truly sets them apart: they make up only 35% of total system cost—yet drive over 70% of operational resistance. That’s why their role in ensuring quality and efficiency is irreplaceable. And when it comes to types? Steel and plastic are the workhorses, each built to dominate in specific conditions, no exceptions.
