RHK Machinery Delivers Stability and Strength from the Ground Up
In the world of heavy equipment, power isn’t enough. What truly drives performance is the ability to stay stable, efficient, and moving—even under the harshest conditions. That’s why the undercarriage system is the backbone of every excavator—and why choosing a dependable excavator undercarriage supplier is essential to operational success.
From compact models like the EX35 to high-capacity giants such as the EX200, undercarriage parts directly affect machine balance, fuel efficiency, and lifespan. At RHK Machinery, delivering long-lasting, precision-engineered undercarriage solutions isn’t just a service—it’s a mission.
What Makes the Undercarriage So Critical?
An excavator’s undercarriage is the heart of the whole structure. This part includes various units such as track chains, bottom rollers, carrier rollers, idlers, and sprockets. These simple parts all play a role by dividing a load, maintaining an effective traction, and switching the energy of impact from one place to another which are caused by the various types of track surfaces and conditions encountered in the areas of machine activity.
Having a weakened undercarriage system can result in huge costs. Building loss due to wear, inefficient fuel consumption, operator exhaustion, and unplanned downtime are just a few of the immediate consequences. At the same time, durable undercarriage components damp the vibrations of machine motion, increase the load-carrying capacity of the machine, and assure a steady flow of the process throughout the service life of the machine.
Engineered for Versatility: From EX35 to EX200
Each machine requires different support. The small models turn, light load handling, and minimal surface impact are always the priorities for machines like the EX35. The undercarriage of this size class of machines has to be flexible and durable.
On the other hand, in the bigger machines such as the EX200, the undercarriage needs to be able to withstand the very tough environment of the application, i.e. rocky quarries, muddy construction areas, etc and thousands of hours of work. Here, the most important things are strength, corrosion resistance, and the exact tolerances of the lousy part of each component.
RHK Machinery is providing custom-made undercarriage solutions for both the large and compact segments, all made of high-grade steel, welded by the robot, and machined by CNC to ensure not only perfect compatibility but also prevent wear and deformation.

- Technical Expertise: Need help identifying the right part or troubleshooting a performance issue? RHK’s engineering support team is available to assist from fitment to installation.
Long-Term Value for Your Machine
Undercarriage parts may account for up to 50% of total maintenance costs over an excavator’s lifespan. That’s why sourcing components from a trusted supplier can significantly reduce your total cost of ownership.
RHK’s commitment to long-wear materials and consistent sizing means fewer replacements, less downtime, and better machine resale value. For example, RHK’s track chains for the EX200 feature oil-sealed links that extend service intervals, while bottom rollers for the EX35 use specialized polymer seals to prevent debris entry.
Serving Industries That Demand More
Whether in construction, mining, agriculture, or demolition, machines face extreme environments that test every component. RHK’s undercarriage systems are built to endure:
- High-impact loads
- Constant shock and vibration
- Wet and corrosive conditions
- Irregular terrain and steep inclines
This level of durability makes RHK the preferred undercarriage partner for heavy-duty users who can’t afford failure in the field.
