Product Description

EX40-2 Heavy-Duty Excavator Track Roller Kit | ISO 6015 Certified Undercarriage Parts with Hardened Rollers

1. What is a roller?

Rollers occupy a pivotal place in belt conveyor arrangements. A wide spectrum of roller varieties exists, and they are deployed in large numbers. Their key functions involve maintaining the conveyor belt and shouldering the weight of the materials being conveyed. Significantly, rollers account for approximately 35% of the overall cost within a belt conveyor setup. Additionally, during the operation of the system, they generate more than 70% of the operational resistance, thereby highlighting the critical significance of the quality of rollers. Generally speaking, contemporary roller designs are constructed from two main materials: steel and plastic.

2. ISO Certification: A Mark of International Quality Assurance

What Does ISO Certification Mean for You?

Our EX22 Pro Kit isn’t just another aftermarket part—it’s a globally recognized standard of excellence. The ISO certification (ISO 9001:2015) ensures every component in this kit undergoes rigorous testing for:

Material Integrity: Cast from high-grade alloy steel to resist corrosion and impact
Manufacturing Precision: Engineered using CNC machining for exacting tolerances
Safety Compliance: Meet or exceed international standards for operational safety

This certification isn’t just a stamp of approval—it’s your guarantee that every track roller, bracket, and fastener in the kit is built to withstand the vibrations, weights, and stresses of daily excavation work.

3. Heat-Treated Rollers: Engineered for Extreme Durability

3.1 The Science Behind Heat Treatment

The core of our Pro Kit’s longevity lies in its heat-treated rollers. Unlike ordinary rollers that soften over time, ours undergo a 3-step heat treatment process:

Austenitization: Heated to 850°C to dissolve carbon into the crystal structure
Quenching: Rapidly cooled in oil to form a hard martensitic structure
Tempering: Reheated to 200°C to balance hardness (HRC 55-60) and toughness

3.2 Performance Benefits You’ll Notice

30% Longer Lifespan: Outlasts non-treated rollers in abrasive environments
50% Better Impact Resistance: Resists dents from rocks and debris
Smoother Operation: Reduced friction means less strain on your excavator’s hydraulics

Whether you’re working on a gravel quarry, a muddy pipeline project, or a frozen construction site, these rollers maintain their structural integrity—keeping your machine moving forward when others start to fail.
