UMG E200C Excavator Overview
The UMG E200C is a mid-sized crawler excavator designed to handle a wide range of earthmoving and material handling applications. Manufactured by UMG Group, a company recognized for producing construction equipment adapted to diverse job site demands, the E200C is built for robustness, efficiency, and maintainability. It typically features a Deutz BF 4M 2012 C diesel engine delivering up to 90kW (122hp) at 2,200rpm. The operating weight ranges from 19.3 to 21.4 tons depending on configuration and stick length, with a bucket capacity between 0.65m³ and 1.25m³. With a maximum digging reach of up to 10,230mm and a digging depth exceeding 7,260mm, this excavator is versatile enough for general construction, mining, and municipal work.
What Are Support Rollers and Why Are They Important
Support rollers, also known as track rollers or bottom rollers, are crucial undercarriage components on tracked excavators. They guide and support the machine’s tracks, distributing the excavator’s weight and enabling smooth movement over uneven terrain. Good support rollers absorb impacts, minimize vibration, and reduce wear on track chains and other moving parts.
If a support roller fails, it can lead to uneven track tension, increased wear on the drive system, track derailment, power loss, or even severe structural damage. Especially on machines like the E200C, which often operate in challenging conditions, reliable rollers are essential for productivity and machine longevity.
Aftermarket Support Roller Selection
When searching for aftermarket support rollers for the UMG E200C, several factors should guide the selection process:
A mining contractor operating several UMG E200C units in Russia encountered premature wear on the original support rollers due to harsh abrasive soil. Switching to aftermarket heavy-duty rollers with improved seals tripled the lifespan of these components, reduced unplanned downtime, and resulted in a measurable decline in operating costs. This scenario highlights the operational benefits of quality aftermarket parts and the importance of preventive maintenance.

Aftermarket Support Roller Selection
When searching for aftermarket support rollers for the UMG E200C, several factors should guide the selection process:
- Compatibility: Ensure the roller matches the E200C’s specifications, including dimensions, mounting hole locations, and maximum working load.
- Materials: High-quality alloy steel or heat-treated components are preferred for resistance to abrasion and impact.
- Sealing: Proper oil sealing systems keep dust and grit out, extending bearing and shaft lifespan.
- Greasing: Some rollers come with lifetime-lubricated bearings, while others require periodic maintenance.
- Warranty: Choose brands that offer warranty coverage for added peace of mind.
- Inspect new rollers for manufacturing defects before installation.
- Replace all worn or damaged rollers at the same time to maintain even track support.
- Regularly check oil seals and lubricate as needed to prevent premature wear.
- After installation, monitor track tension and adjust according to manufacturer recommendations.

Glossary of Terms
- Support Roller / Track Roller: Undercarriage component that supports and guides the tracks of an excavator.
- Undercarriage: The bottom assembly of a tracked vehicle, including tracks, rollers, idlers, and drive sprockets.
- Mounting Hole: The location where bolts or pins secure the roller to the track frame.
- Oil Seal: Device that prevents oil leakage and blocks contaminants from entering the roller’s internal bearings.
- Track Tension: The tightness of the excavator’s tracks, which affects performance and component life.
