232/54000 Excavator parts JCB802 track roller

The JCB802track roller is an important part of the JCB802 excavator chassis. It is mainly used to support the weight of the whole machine and evenly distribute the weight of the machine on the track plate to ensure the stable operation of the excavator. It plays a role in restricting the tracks and preventing lateral slippage during operation, and forces the tracks to slip on the ground when the machine is turning. The supporting wheel is usually composed of wheel body, shaft, bearing and sealing ring made of high-strength alloy steel, which has high hardness and abrasion resistance and can adapt to the harsh working environment.
