The Caterpillar 609-5428 Single Flange Track Roller is a genuine OEM-specification undercarriage component designed for Caterpillar 336 and 340 series excavators. 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 336 and 340 series are large excavators used in mining, construction, quarrying, and demolition 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.
