Hitachi Zx120 Undercarriage Parts for Bulldozer Heat-treated Track Rollers 9066508

1. What is a roller?

✔ Functional Positioning: Rollers undertake the dynamic support function for the conveyor belt and the weight of transported materials, serving as the foundational components for maintaining continuous operation of the conveying system.

✔ Cost Proportion: The procurement and maintenance costs of rollers account for 35% of the total installation cost of a belt conveyor (based on typical operating conditions), forming a critical part of the equipment’s life-cycle cost.

✔ Energy Consumption Impact: During operation, frictional resistance generated by roller sets constitutes over 70% of the system’s total running resistance, directly affecting equipment energy consumption and operational economy.

✔ Quality Relevance: The manufacturing precision, sealing performance, and material durability of rollers directly determine equipment failure rates (e.g., bearing failure, abnormal wear), making them a key control point in system reliability design.

✔ Material System: Currently, mainstream application materials are steel (high strength, heavy-load resistance, accounting for ~85%) and engineering plastics (corrosion resistance, low noise, suitable for special working conditions). Their performance parameters require differentiated selection based on conveying media and environmental conditions.

2. Track Rollers Excavator Advantages / Features

• Through quench-tempering processes to ensure excellent mechanical properties, high strength and superior wear resistance to bending and breakage.
• Surface hardness HRC40-55 for reduced wear and longer life, adding value to your products further to your business by maximizing durability of your products.
• Track roller with precision engineered components, careful heat-treatment, and lifetime sealing system, the rollers are assured of long life. The roller shells are forged from deep hardening steel and are designed to resist bell mouthing. All rollers carry the manufacturer's warranty.
