PC2000 BOTTOM ROLLER PART NO.:21T-30-00010
Product Overview
Part Number: 21T-30-00010
Fit Equipment: Komatsu PC2000 Heavy Mining Excavator
This track roller (bottom roller) is a heavy-duty aftermarket replacement undercarriage wear part exclusively engineered for Komatsu PC2000 large mining excavators. It is forged from high-alloy steel and treated with full-surface deep quenching heat treatment, equipped with a triple-layer leak-proof oil seal structure. The roller bears the full weight of the whole machine and ensures reliable track chain movement under harsh heavy-load working conditions of mines and stone quarries.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller width, spindle length and mounting hole sizes are precisely processed to perfectly match Komatsu PC2000 excavators. Direct bolt-on installation is available without cutting or secondary modification.
Ultra Deep Hardened Roller Surface
The roller body adopts carburizing quenching treatment to achieve ultra-high surface hardness and superior wear resistance, greatly extending service life on rocky mining job sites.
Triple Multi-Layer Oil Seal System
High-temperature, mud and water resistant composite rubber seals effectively block sediment ingress and grease leakage, significantly prolonging lubrication maintenance intervals.
Oversized Heavy-Duty Internal Bearing
Delivers powerful heavy-load bearing capacity and smooth steady rotation to prevent track shaking, jumping and track chain derailment.
Strict Factory Full Inspection
Each bottom roller undergoes hardness testing, hydraulic leak testing and dimensional calibration before packaging to guarantee consistent uniform quality.
