Mini Excavator Bottom Assembly Track Roller For Kobelco SK45 OEM Excavator Undercarriage Parts Heavy Duty Forged Steel
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 rollers and carrier rollers are manufactured from 40Mn2, 40MnB, or 50Mn steel selected for operational conditions. Prior to final heat treatment, rollers undergo precision forging with normalizing to achieve HRC52-56 surface hardness and a hardened layer depth exceeding 7-10mm (HRC45), ensuring contact surfaces possess superior durability, impact resistance, and wear resistance. Integration of high-performance floating seals and a robust lubrication system enables reliable operation under extreme climatic conditions ranging from -45°C to +120°C, requiring zero maintenance for prolonged component life. For track rollers specifically, welding precedes precision machining on vertical CNC lathes, eliminating concentricity errors; this sequence provides unmatched quality advantages over post-welding machining, guaranteeing resistance to rapid wear and maximizing service life.
