| Applicable Excavator Model | PC300-5 / PC300-6 |
| 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 |
PC300-5 and PC300-6 excavators are designed for heavy-load operations, widely used in large-scale earthmoving projects, quarry mining, road reconstruction and complex muddy working sites. Continuous gravel friction, long-term water immersion and frequent impact bring high load pressure to undercarriage parts. This top roller is professionally built to adapt to harsh working conditions and maintain stable performance during prolonged operation.
Adopt high-strength one-piece forging steel blank to withstand heavy operational loads. Dual standard heat treatment is adopted: integral quenching improves surface hardness for excellent abrasion resistance; tempering eliminates internal metal residual stress to enhance structural 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 fleet operates multiple PC300-5 and PC300-6 excavators for quarry and infrastructure projects. After equipped with our OEM-spec top rollers, all undercarriage parts keep stable operation over 1800 working hours with excellent sealing condition and complete roller shell, cutting annual undercarriage maintenance cost by 33%.
