Product Description

Volvo EC290 Excavator Undercarriage OEM Track Roller: High-Precision Bottom Roller for Heavy-Duty Applications




1. What is a roller?

As key functional elements of belt conveyor systems, rollers play a decisive role in overall operational efficiency.

Functional Role: Rollers serve the critical role of dynamic support for both the conveyor belt and the payload, acting as indispensable foundational components to sustain uninterrupted conveying operations.

Cost Significance: Representing 35% of a belt conveyor’s total installation cost (based on standard operational parameters), roller procurement and maintenance constitute a substantial portion of the equipment’s life-cycle cost framework.

Energy Performance Impact: Roller assemblies generate over 70% of the system’s total operational frictional resistance, directly influencing energy consumption levels and long-term operational cost-effectiveness.

Reliability Criticality: Parameters such as manufacturing precision, sealing integrity, and material durability directly dictate failure rates (e.g., bearing malfunction, premature wear), positioning rollers as a core control parameter in system reliability engineering.

Material Portfolio: The primary material choices remain steel (characterized by high-strength load-bearing capacity, accounting for ~85% of applications) and engineered plastics (offering corrosion resistance and low-noise operation for specialized environments). Material selection must be tailored to conveyanced media properties and environmental conditions.



2. Track Rollers Excavator Advantages / Features

Track roller and Carrier roller materials are selected from 40Mn2, 40MnB, or 50Mn based on operational conditions. Prior to overall heat treatment, the rollers undergo precision forging with normalizing to achieve HRC52-56 surface hardness and a hardened layer depth exceeding 7-10mm (HRC45). This process ensures the contact surfaces exhibit superior durability, impact resistance, and surface wear resistance.

High-performance floating seals and a robust lubrication system are integrated to adapt to diverse climatic and temperature environments. The rollers are capable of operating under extreme conditions or climates ranging from -45℃ to 120℃, requiring zero maintenance for prolonged component reliability.

For Track Rollers, welding is performed before precision machining on vertical CNC turning lathes, eliminating concentricity errors. This sequential process offers unmatched quality advantages over pre-welding machining methods, guaranteeing resistance to rapid wear and significantly extending product service life.
