This carrier top roller is a 1:1 OEM direct replacement for EX200-2 excavator, with official part number 9062406. 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 EX200-2 equipment fleets.
| OEM Part Number | 9062406 |
| Applicable Model | EX200-2 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 applied in municipal engineering, quarry operations and road maintenance. Long-term muddy water immersion, gravel friction and continuous impact load will lead to track shaking, track sagging, seal leakage and shaft jamming on ordinary rollers. This component is manufactured to adapt to complex working conditions and keep stable operating performance.
We use one-piece integral forging steel blank for solid structure. Dual heat treatment is adopted in production: quenching enhances surface hardness to resist abrasive wear; tempering eliminates internal stress and avoids shell cracking under repeated impact. All mounting holes and contact surfaces are processed by CNC equipment, with machining error controlled within 0.01mm, fully consistent with original factory dimensions.
A local construction service team operates multiple EX200-2 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. 9062406 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.
