Replacing one roller is a good time to inspect the entire undercarriage. Remember that worn sprockets and tracks drastically accelerate the wear of new rollers. Check our offer of KERTRACK undercarriage parts to comprehensively maintain your machine.
Track rollers support the entire weight of the mini excavator on the tracks, guiding them and ensuring smooth travel. They operate in extreme conditions, constantly exposed to impacts, abrasion, and contamination.
One seized roller can lead to track damage. Replace it if you notice:

Yes, it is possible. However, keep in mind that the other rollers have worked just as long and may be close to failure. Replacing one roller is an ideal time to inspect the others.
2. How do I know if my machine uses single or double flange rollers?The best way is to check visually. Double flange (outer guide) rollers are usually mounted at the front and back of the undercarriage frame, while single flange (center guide) rollers, like this one, are located between them.
3. What causes the most damage to track rollers?The most common causes of premature wear are: operating in very abrasive terrain (sand, rocks), excessive track tension, and contamination (mud, concrete) that is not regularly cleaned from the undercarriage.
