EX1200-6 BOTTOM ROLLER PART NO.:4666752
Product Overview
Part Number: 4666752
Fit Machine: Hitachi EX1200-6 Heavy Mining Excavator
This track roller (bottom roller) is a heavy-duty aftermarket replacement undercarriage wear part exclusively engineered for Hitachi EX1200-6 large open-pit mining excavators. It is forged from high-strength alloy steel and processed with full-surface deep carburizing quenching heat treatment, fitted with a triple-layer anti-leak oil seal system. The roller bears the full weight of the machine and enables stable track chain movement under severe heavy-load conditions of open-pit mines and stone quarries.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller width, spindle length and mounting hole dimensions are precisely processed to fit Hitachi EX1200-6 excavators seamlessly. Direct bolt-on installation is available without cutting or any extra modification.
Ultra Deep Hardened Roller Surface
The deep carburizing quenching treatment delivers ultra-high surface hardness and superior wear resistance, significantly extending service life on rocky mining job sites.
Triple Multi-Layer Mud-Proof Oil Seal
High-temperature and sediment-resistant composite rubber seals effectively block mud and water ingress while preventing grease leakage, greatly prolonging maintenance intervals for mining production operations.
Oversized Heavy-Duty Internal Bearing
