| OEM Part Number | 207-30-00150 |
| Applicable Excavator Model | PC200LC-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, heavy-load earthmoving terrain |
| Installation Type | Plug-and-play OEM direct replacement |
PC200LC-7 long track excavators undertake heavier track load compared to standard chassis models, widely used in large earthmoving projects, quarry mining, highway construction, and harsh muddy working sites. Continuous gravel friction, long-term water immersion, and frequent walking impact bring higher load pressure to undercarriage rollers. This reinforced top roller is customized for long chassis heavy-load working demands, maintaining stable running performance at all times.
Manufactured using high-strength one-piece forging steel blanks to bear extra heavy loads of long track machines. Dual standard heat treatment is adopted: integral quenching improves surface hardness for outstanding wear resistance; tempering eliminates internal metal residual stress to enhance overall impact toughness. All mounting holes and matching surfaces are processed by high-precision CNC equipment, with machining tolerance strictly controlled within 0.01mm, fully consistent with original factory OEM standards.
A large engineering construction fleet operates plenty of PC200LC-7 long track excavators for quarry projects. After being equipped with our OEM-spec top rollers, all undercarriage parts maintain stable operation over 1800 working hours with excellent sealing condition and complete roller shell, cutting annual undercarriage maintenance cost by 33%.
Yes, OEM part number 207-30-00150 is fully matched with PC200LC-7 long chassis model, no extra adjustment needed.
Yes, it can also fit standard PC200-7 excavator with the same installation dimension.
Yes, we can provide professional heat treatment reports and dimensional inspection reports to support customer quality inspection and customs clearance.
