Product Overview
Part Number: 9242601
Fit Machine: Hitachi EX400 Heavy Excavator
This track roller (bottom roller) is a heavy-duty aftermarket replacement undercarriage wear part designed for Hitachi EX400 crawler excavators. Forged from high-strength alloy steel with full-surface deep carburizing quenching heat treatment, it adopts a triple-layer anti-leak oil seal system. The roller bears the full weight of the excavator and maintains stable track chain operation on stone quarries, mining zones and heavy earthmoving construction sites.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller width, spindle length and mounting hole sizes are precisely machined to perfectly fit Hitachi EX400 excavators. Direct bolt-on installation is available without cutting or extra modification.
Ultra Deep Hardened Roller Surface
Deep carburizing quenching treatment achieves high surface hardness and superior wear resistance, greatly extending service life on rocky and muddy working sites.
Triple Multi-Layer Mud-Proof Oil Seal
High-temperature and sediment-resistant composite rubber seals block mud and water ingress while preventing grease leakage, significantly prolonging maintenance intervals.
Oversized Heavy-Duty Internal Bearing
Delivers powerful load-bearing capacity and smooth steady rotation to avoid track shaking, jumping and track chain derailment.
