PC400 TOP ROLLER PART NO.:207-30-00030
Product Overview
Part Number: 207-30-00030
Fit Machine: Komatsu PC400 Heavy Excavator
This carrier roller (top roller) is a heavy-duty aftermarket replacement undercarriage wear part exclusively engineered for Komatsu PC400 crawler excavators. Forged from high-strength alloy steel and treated with full-surface deep quenching heat treatment, it is fitted with a triple-layer anti-leak oil seal system. The roller supports the full weight of the upper track chain, minimizing track vibration, abrasion and derailment under harsh working conditions including mining, stone quarries and heavy earthmoving projects.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller diameter, spindle length and mounting hole sizes are precisely machined to perfectly fit Komatsu PC400 excavators. Direct bolt-on installation is available without cutting or extra modification.
Ultra Deep Hardened Roller Surface
The roller body undergoes deep carburizing quenching treatment to achieve ultra-high surface hardness and superior anti-wear performance, extending service life significantly on rocky mining job sites.
Triple Multi-Layer Mud-Proof Oil Seal
High-temperature, mud and sediment resistant composite rubber seals effectively block water ingress and grease leakage, greatly prolonging lubrication maintenance intervals.
Oversized Heavy-Duty Internal Bearing
Features exceptional heavy-load bearing capacity and smooth steady rotation to prevent track jumping and track chain detachment during heavy-duty operations.
Strict Factory Full Inspection
Each top roller passes hardness testing, hydraulic leak testing and dimensional calibration before packaging to guarantee consistent uniform quality.
