Excavator rollers are the core load-bearing and guiding components of the crawler track system. Their design and maintenance directly impact the equipment's stability and track life. The upper carrier roller is mounted on the top of the crawler frame, supporting the upper travel of the track chain and reducing track sag during operation. A double-flange structure prevents lateral derailment of the track, and the shaft ends are equipped with triple labyrinth seals and lithium-based grease lubrication ports as standard. The lower rollers are located at the bottom of the crawler frame, directly bearing the weight of the machine and ground impact loads.
