Excavator parts JS30 Track roller

The JS30 track roller is an important part of the chassis system of the JS30 excavator. Its main function is to support the weight of the excavator and evenly distribute the weight of the machine body on the track plate to ensure stable operation of the excavator during operation. It restricts the lateral movement of the tracks, prevents the tracks from slipping off, and assists the tracks to slide smoothly on the ground when the machine is turning. The supporting wheel is usually made of high-strength alloy steel wheel body, axle, bearings and seals and other components, with high hardness and abrasion resistance, and can adapt to the harsh working conditions of the excavator. There are several brands on the market that offer counterweight wheels for the JS30.
