The Caterpillar 288-0935 Double Flange Track Roller is a genuine OEM-specification undercarriage component designed for the Caterpillar D6R dozer. This double 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 double flange design provides enhanced track guidance, keeping the track chain properly aligned during operation, which is especially beneficial for dozer applications on side slopes.
