Bottom Rollers
Replacement Bottom Rollers and Track Rollers
Bottom rollers support the machine along the lower track frame and guide the chain or rubber track as it travels. Worn flanges, leaking seals, seized bearings, and uneven rolling surfaces can affect alignment and accelerate wear throughout the undercarriage.
Bottom Roller Applications
- Excavators and mini excavators
- Crawler dozers and loaders
- Compact track loaders and other tracked equipment
Review the complete system at the undercarriage parts hub. Roller style, mounting pattern, flange arrangement, and machine serial range should be verified before ordering.
Information Needed for Fitment
Send the make, model, serial number, roller location, mounting measurements, and clear photos through the Part Finder. A casting or part number is especially helpful when available.
Inspect Rollers Before They Damage the Track
Common Signs of Roller Wear
Look for oil leakage, flat spots, excessive side movement, broken flanges, unusual noise, and uneven track-chain contact. Early replacement can help protect the rails and maintain correct tracking.
