Product Overview
The bottom track roller carries the machine weight along the lower track run and keeps the track supported. When evaluating a possible failure, pay attention to these concerns: a seized roller, oil leakage, uneven track wear or a flat-spotted tread. Similar problems can have other causes, so check the surrounding system before deciding to replace this part.
Before replacing it, compare roller diameter, bolt spacing, track type and machine serial number. This helps ensure the new component matches the equipment already on the machine rather than just a similar-looking part.
