Subtitle: Discover how RHK Machinery manufactures high-performance track rollers, track links, and full undercarriage solutions as a trusted global excavator undercarriage factory.
In earthmoving, mining, and construction, what’s beneath the machine is just as important as what’s on top. Undercarriage components bear the full weight of the excavator and absorb relentless stress from rugged terrain. That’s why a dependable excavator undercarriage factory is the foundation of any successful equipment fleet—and why RHK Machinery is the trusted name behind durable, precision-built undercarriage parts worldwide.

Undercarriage Engineering You Can Trust
As a specialized excavator undercarriage factory, RHK Machinery focuses on one thing: long-lasting performance under pressure. Our product range includes:
- Track rollers (top and bottom)
- Track link assemblies
- Carrier rollers
- Sprockets and idlers
- Track shoes and bolts
Each part is forged from high-grade alloy steel, heat-treated for hardness, and machined to exacting tolerances. The result? Components that reduce wear, extend service intervals, and withstand harsh field conditions—from muddy worksites to rock-strewn quarries.
Track Rollers Built for Load and Longevity
A critical part of every excavator’s undercarriage is the track roller. These components support the weight of the machine and ensure the smooth movement of the tracks over varied terrain. At RHK Machinery, our rollers are manufactured with hardened shafts and seals designed to retain grease and keep contaminants out—key to prolonged service life.
Whether you need single flange, double flange, or customized track roller sizes for specific OEM models, we offer options for:
- 1–50 ton class excavators
- Mini, crawler, and hydraulic types
- Hitachi, Komatsu, CAT, Hyundai, Doosan, and more
Each roller undergoes dynamic load testing and surface treatment to ensure reliability in high-friction environments.
Precision Track Link Assemblies for Consistent Performance
Our track link assemblies are another cornerstone product, offering stability, correct pitch tolerance, and optimal contact with sprockets. RHK’s track link systems are assembled with press-fitted pins and bushings, induction-hardened for durability and resistance to elongation.
Features include:
- Heavy-duty sealing systems
- Pre-lubricated or dry variants
- CNC-machined tolerances
- Compatibility with leading excavator brands
We also offer replacement track link kits for older equipment or custom machinery, ensuring minimal downtime and quick installation.
