What Does the Carrier Roller Do on a DH220?
Carrier rollers — also known as upper rollers — are located at the top of the excavator’s undercarriage system. Their job is to support and guide the upper portion of the track chain, preventing it from sagging and reducing overall wear on the entire undercarriage.
For the DH220, which often works under rugged outdoor conditions, having a properly functioning upper roller is essential for:
- Maintaining track alignment during operation
- Reducing friction and preventing premature track wear
- Enhancing machine stability, especially when traveling over uneven terrain

OEM Compatibility and Mounting Specifications
This carrier roller is designed specifically for Doosan DH220 excavators. It follows OEM standards for size and mounting dimensions, ensuring easy installation and compatibility with original equipment. The part typically corresponds to OEM reference number 2270-1011, though cross-checking with your machine's serial is advised. We also support customized orders with logo engraving and technical drawings for OEM clients.
Use Cases and Working Conditions
The DH220 carrier roller is ideal for excavators working in:
- Earthmoving and excavation
- Sand and gravel pits
- Road construction
- Utility trenching
In these scenarios, maintaining track support on the upper side reduces downtime and enhances operator comfort by preventing vibration and drift.
Maintenance Tips for Long-Term Performance
Although carrier rollers endure less abrasion than bottom rollers, they still need periodic inspection. To extend their working life:
- Clean the roller area regularly to avoid debris buildup
- Monitor for grease leaks and abnormal noises
- Rotate the roller manually to check for resistance
- Replace rollers in pairs for balance when necessary
These steps will ensure stable performance of your Doosan DH220 excavator on all terrains.
