Product Overview
Part Number: 9235892
Fit Machine: Hitachi ZX210 Medium Crawler Excavator
This carrier roller (top roller) is a heavy-duty aftermarket replacement undercarriage wear part custom-made for Hitachi ZX210 medium excavators. Forged from high-strength alloy steel and treated with full-surface quenching heat treatment, it adopts a double leak-proof oil seal design. The roller supports the weight of the upper track assembly and suppresses track vibration and abrasion in various construction scenarios.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller diameter, spindle length and mounting hole sizes are precisely processed to perfectly fit Hitachi ZX210 excavators. Direct bolt-on installation is available without cutting or secondary modification.
Hardened Roller Surface
Carburizing quenching treatment on the roller body delivers high surface hardness for extended service life on muddy and rocky construction job sites.
Multi-Layer Oil Seal System
High-temperature resistant rubber seals effectively block mud ingress and grease leakage, significantly prolonging lubrication maintenance intervals.
Heavy-Duty Internal Bearing
Offers excellent load-bearing capacity and smooth steady rotation to prevent track jumping and track chain detachment.
Strict Full Factory Quality Inspection
Each top roller undergoes pressure testing, leak testing and hardness inspection before shipment to ensure consistent stable quality.
