SK200 TOP ROLLER PART NO.:LQ50000110
Product Overview
Part Number: LQ50000110
Fit Machine: Kobelco SK200 Medium Excavator
This carrier roller (top roller) is a heavy-duty aftermarket replacement undercarriage wear part for Kobelco SK200 crawler excavators. Forged from high-strength alloy steel and processed with full-surface quenching heat treatment, it features a double multi-layer leak-proof oil seal structure. The roller supports the weight of the upper track assembly and minimizes track vibration, abrasion and derailment during various construction operations.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller diameter, spindle length and mounting hole sizes are precisely machined to perfectly fit Kobelco SK200 excavators. Direct bolt-on installation is available without cutting or secondary modification.
Deep Hardened Roller Surface
Carburizing quenching treatment is applied to the roller body to deliver high surface hardness, extending service life significantly on muddy, rocky construction and quarry sites.
Double-Layer Anti-Leak Oil Seal
High-temperature resistant rubber seals block mud and sediment ingress, effectively prevent grease leakage and greatly prolong lubrication maintenance intervals.
Heavy-Duty Internal Bearing
Boasts powerful load-bearing capacity and smooth stable rotation to avoid track jumping and track chain detachment.
Strict Factory Full Inspection
Each top roller undergoes hardness testing, pressure testing and leak testing before shipment to guarantee consistent uniform quality.
