This carrier top roller is a 1:1 OEM direct replacement for ZX200 excavator, with official part number 9302198. No cutting, drilling or secondary modification is required during installation. It adapts to long-term heavy-duty operation and resolves common undercarriage running issues of ZX200 equipment fleets.
| Item | Specification |
|---|---|
| OEM Part Number | 9302198 |
| Applicable Model | ZX200 Excavator |
| Machining Tolerance | ±0.01mm CNC ultra-precision machining |
| Heat Treatment Process | Overall quenching + stress relief tempering |
| Working Scenarios | Muddy construction site, gravel quarry, road renovation, rough earthmoving terrain |
| Installation Type | Plug-and-play OEM direct replacement |
This excavator model is widely used in municipal engineering, quarry operations and road maintenance. Long-term muddy water immersion, gravel friction and continuous impact load will cause ordinary rollers to develop track shaking, track sagging, seal leakage and shaft jamming. This component is built to suit complex working conditions and maintain stable operation.
One-piece integral forging steel blank is adopted to ensure structural stability. Dual heat treatment is applied: quenching improves surface hardness against abrasive wear; tempering eliminates internal stress to prevent shell cracking under repeated impact. All mounting holes and contact surfaces are CNC processed with machining error within 0.01mm, fully matching original factory dimensions.
A local construction service team operates multiple ZX200 excavators. Generic rollers used before failed within 690-840 working hours. After switching to our products, the rollers run stably for over 1800 working hours without faults, reducing annual undercarriage maintenance costs by 33%.
A: Yes. Part No. 9302198 matches the model perfectly, no extra adjustment needed during installation.
A: Most generic products omit tempering and have dimensional tolerance above 0.05mm. Our dual heat treatment and 0.01mm high-precision machining ensure reliable performance in harsh environments.
A: Yes. We supply heat treatment test reports and dimensional inspection reports for all bulk shipments.
