Excavator parts CX75 track roller

Case CX75 track roller is an important part of Case CX75 excavator chassis, 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 prevents the tracks from slipping off laterally and forces the tracks to slip on the ground when the machine is turning. It usually consists of wheel body, shaft, bearing, sealing ring and other components. The wheel body is usually made of high-strength alloy steel, which is subject to a special heat treatment process to provide high hardness and abrasion resistance to adapt to the harsh working environment.
