This 81N6-13010 R210 lower track roller is a durable chassis load-bearing spare part customized for R210 series excavator track system maintenance and replacement. Unlike common low-carbon steel track rollers with poor comprehensive performance, this bottom roller uses premium 35MnB alloy steel as full raw material. This professional mechanical steel balances excellent wear resistance, impact toughness and compression resistance, perfectly matching medium and heavy load working conditions of R210 chassis.
It delivers stable long-term supporting performance for daily earthwork, road construction and muddy uneven sites, reducing frequent part replacement downtime for construction equipment.
| Parameter Item | Factory Standard Specification |
|---|---|
| Part Number | 81N6-13010 |
| Applicable Equipment | R210 Series Excavator |
| Core Raw Material | Full 35MnB High-strength Alloy Steel |
| Processing Flow | Rough Forging + Precision Finishing + Integral Heat Treatment |
| Surface Hardness | HRC 52-58 |
| Dimensional Tolerance | ±0.02mm |
| Material Advantage | Anti-wear, anti-impact, crack-resistant under cyclic load |
| Applicable Scenarios | General construction, earthmoving, muddy road, medium heavy load sites |
Most budget aftermarket track rollers adopt ordinary carbon steel with unstable material composition. Such rollers suffer fast surface abrasion, brittle cracking and shaft damage easily under cyclic track vibration and moderate heavy load.
Our 81N6-13010 track roller sticks to pure 35MnB alloy steel for whole body production. Every batch of raw steel undergoes strict chemical composition inspection before production. We match targeted tempering and quenching process based on alloy material characteristics, avoiding material performance attenuation, and solving the core defect of short service life for ordinary carbon steel chassis rollers.
This 35MnB alloy steel track roller is perfectly applied to R210 series excavator chassis load-bearing replacement and routine undercarriage overhaul. All finished rollers are treated with anti-rust oil, sealed with waterproof protective film and packed with reinforced wooden cases for long-distance ocean transportation.
We provide material inspection certificates, sample testing and bulk OEM wholesale services, supplying cost-effective and durable chassis load-bearing parts for global engineering machinery dealers and repair workshops.
