ZX75 TOP ROLLER PART NO.:9163909
Product Overview
Part Number: 9163909
Fit Machine: Hitachi ZX75 Mini Excavator
This carrier roller (top roller) is a heavy-duty aftermarket replacement undercarriage wear part exclusively engineered for Hitachi ZX75 compact mini excavators. Forged from high-strength steel and processed with full-surface quenching heat treatment, it is fitted with a double multi-layer leak-proof oil seal assembly. The roller bears the weight of the upper track assembly and reduces track vibration and abrasion during landscaping, farm improvement and small municipal construction projects.
Core Advantages
Precision Machined Replacement Installation Dimensions
Roller diameter, spindle length and mounting hole sizes are precisely machined to perfectly fit Hitachi ZX75 excavators. Direct bolt-on installation is available without cutting or secondary modification.
Deep Hardened Roller Surface
Carburizing quenching treatment on the roller body delivers high surface hardness, greatly extending service life on muddy and rocky construction sites.
Double Leak-Proof Oil Seal System
High-temperature resistant rubber seals block mud and water ingress, effectively prevent grease leakage and significantly prolong lubrication maintenance intervals.
Heavy-Duty Internal Bearing
Features powerful load-bearing capacity and smooth steady rotation to avoid track jumping and track chain detachment.
Strict Factory Full Inspection
Each top roller undergoes hardness testing, pressure testing and hydraulic leak testing before packaging to guarantee consistent uniform quality.
