The Caterpillar 288-0934 Single Flange Track Roller is a genuine OEM-specification undercarriage component designed for the Caterpillar D6R dozer. This single flange track roller (bottom roller) is a critical load-bearing component that supports the machine's weight and guides the track chain during operation.
The D6R is a medium-to-large dozer used in construction, land clearing, heavy dozing, and mining support applications. The single flange design provides effective track guidance while balancing weight and durability. Manufactured from high-strength alloy steel with induction-hardened tread surfaces, it delivers maximum wear resistance in abrasive conditions.
