Detailed Product Description
The SEM 6031615 Track Roller (Double Flange) is a genuine OEM-specification undercarriage component designed for the SEM 822D bulldozer/tractor. 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 SEM 822D is a large bulldozer used in construction, earthmoving, land clearing, 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.
