Ultra Track Triple Flange Bottom Rollers – Heavy-Duty Support Where It Counts. Designed for demanding applications, Ultra Track triple flange bottom rollers provide superior stability and support for your machine’s undercarriage. Manufactured to meet or exceed OEM standards, these rollers are equipped with high-quality double lip seals that effectively block out debris and retain lubrication for longer service life. Triple flange rollers are ideal for machines requiring extra guidance and load distribution, especially in uneven or high-impact terrain. They carry the weight of the machine, guide the track, and ensure smooth, reliable operation during travel and digging. For optimal undercarriage performance, we recommend inspecting all rollers regularly and replacing worn components in sets to maintain even wear and maximize longevity.
