Product Overview
The pair of bottom track rollers supports the lower track run and spreads machine weight along the undercarriage. When evaluating a possible failure, pay attention to these concerns: rough travel, oil leakage or uneven tread wear from worn rollers. Similar problems can have other causes, so check the surrounding system before deciding to replace this part.
Before replacing it, compare mounting hole spacing, roller size and machine serial number. This helps ensure the new component matches the equipment already on the machine rather than just a similar-looking part.
