وصف المنتج
PC200-7 Top Roller OEM Replacement 207-30-00150
This heavy-duty carrier top roller is a 1:1 OEM direct replacement for PC200-7 excavator, with standard OEM part number 207-30-00150. Perfectly matching original mounting dimensions and bolt holes, it requires no cutting, drilling or any on-site modification. It effectively supports track operation, avoids track sagging and vibration, and optimizes undercarriage running performance for long-working excavator fleets.
Specification
| Item | Specification |
|---|---|
| OEM Part Number | 207-30-00150 |
| Applicable Excavator Model | PC200-7 |
| Machining Tolerance | ±0.01mm CNC ultra-precision machining |
| Heat Treatment Process | Overall quenching + stress relief tempering |
| Applicable Working Scenarios | Muddy construction site, gravel quarry, road renovation, rough earthmoving terrain |
| Installation Type | Plug-and-play OEM direct replacement |
Applicable Working Environments
PC200-7 excavators are widely used in medium and large earthmoving projects, quarry exploitation, municipal road reconstruction and muddy job sites. Long-term gravel friction, muddy water erosion and continuous walking load bring heavy pressure to undercarriage parts. This top roller is professionally manufactured to adapt to various harsh working conditions and maintain stable long-term operation.
Core Production & Heat Treatment Process
Adopt high-strength one-piece forging steel blank to enhance overall structural stability and impact resistance. Dual standard heat treatment is adopted: integral quenching improves surface hardness for long-term abrasion resistance; tempering eliminates internal metal residual stress to keep complete structural toughness. All mounting holes and matching surfaces are processed by high-precision CNC equipment, with machining tolerance strictly controlled within 0.01mm, fully fitting original factory installation standards.
On-site Installation Steps
- Raise the excavator track with a hydraulic jack to separate track from ground and release partial track tension
- Remove fixing bolts of the old top roller, take out damaged roller and clean dust and sediment on the mounting base
- Place the new top roller in original position, align reserved bolt holes accurately
- Lock all fixing bolts with standard torque, reset track tension and conduct track idle running test
- Check no abnormal vibration or friction noise to complete installation
Product Advantages
- Accurate OEM size matching stabilizes track running and reduces walking vibration
- Reinforced floating seal structure isolates external dust and muddy water steadily
- Complete dual heat treatment improves overall durability and extends service cycle
- High structural strength adapts to heavy-load operation in various construction sites
- Direct bolt-on installation saves on-site maintenance time and labor cost
Customer Application Case
A Southeast Asian engineering fleet operates multiple PC200-7 excavators. After equipped with our OEM-spec top rollers, all undercarriage parts keep stable operation over 1800 working hours with good sealing performance and intact roller shell, cutting annual undercarriage maintenance expenditure by 33%.
Frequently Asked Questions
