5. Product Features & Advantages:
High wear resistance: Hardened roller surface effectively reduces abrasion during long-distance traveling on gravel, muddy and mining terrain.

Excellent sealing performance: Multi-layer oil seal structure prevents oil leakage, dust, mud and water intrusion, extending service life.
Strong load-bearing capacity: Robust casting structure, resistant to impact and deformation under heavy load working conditions.

Stable rotation: Precision matching of shaft and bushing ensures flexible rotation, lowers walking resistance and avoids track deviation.
Direct replacement: Consistent with original size and installation structure, no modification required for quick installation.

6. Function & Application:
The track roller is an essential undercarriage component of Hyundai RB220LC9S excavator. It supports the weight of the machine and slides on the track link during operation. Ideal replacement for worn, oil-leaking or damaged original bottom rollers for engineering construction, earthmoving and quarry projects.
