Product Overview
Part Number: 203-30-00010
Fit Machine: Komatsu PC100 Medium Excavator
This track roller (bottom roller) is a heavy-duty aftermarket replacement undercarriage wear part designed for Komatsu PC100 crawler excavators. Forged from high-strength alloy steel with full-surface deep carburizing quenching heat treatment, it is fitted with a double-layer anti-leak oil seal system. The roller bears the full weight of the excavator and ensures smooth track chain operation in municipal, earthmoving and small quarry construction scenarios.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller width, spindle length and mounting hole sizes are precisely machined to perfectly fit Komatsu PC100 excavators. Direct bolt-on installation is available without cutting or secondary modification.
Deep Hardened Roller Surface
Deep carburizing quenching delivers high surface hardness and superior wear resistance, greatly extending service life on muddy and rocky construction job sites.
Double Multi-Layer Mud-Proof Oil Seal
High-temperature and sediment-resistant composite rubber seals effectively block mud and water ingress while preventing grease leakage, significantly prolonging maintenance intervals.
Heavy-Duty Internal Bearing
Offers powerful load-bearing capacity and smooth stable rotation to prevent track shaking, jumping and track chain derailment.
