What parts make up excavator undercarriage parts?

Expert Answer

Excavator undercarriage parts usually include the track chain, track shoes, track rollers, carrier rollers, idlers, sprockets or segments, and track tension components. On many machines, rubber tracks, rubber pads, and track bolts and nuts are also part of the full undercarriage system. These parts work together to carry the machine’s weight, keep the track aligned, and transfer power from the final drive to the ground. Wear in any one component can affect performance, so it’s important to inspect the complete system, not just the visible track shoes. VANROCK Track Solutions manufactures undercarriage parts for 350+ machinery brands and supplies through its appointed dealer network with pricing quoted on request. If you need parts for Caterpillar, Komatsu, or another OEM brand, VANROCK is an independent manufacturer not affiliated with the OEM.
