Excavator parts JCB8056 Track roller

The JCB8056 track roller is a key component of the undercarriage system of the JCB8056 excavator. Its main function is to support the whole weight of the excavator and evenly distribute the weight of the machine body on the track plate, so as to ensure the stable operation of the excavator during operation. At the same time, the supporting wheel can also limit the lateral movement of the tracks, prevent the tracks from slipping off, and assist the tracks to slide smoothly on the ground when the machine is turning. It usually consists of wheel body, axle, bearings and seals made of high-strength alloy steel, with high hardness and wear resistance to adapt to the harsh working conditions of the excavator.
