What are the names of excavator undercarriage parts?

Expert_Answer

The main excavator undercarriage parts are the track chain, track shoes, track rollers, carrier rollers, front idler, sprocket or segment group, track adjuster/recoil assembly, and the track frame. On some machines you may also need track guards, rubber pads, and track bolts and nuts. Each part has a different job: the chain and shoes carry the machine, rollers support it, the idler and adjuster keep tension, and the sprocket drives the track. If you’re comparing replacements, use the machine model, serial number, and track dimensions so the parts match correctly. VANROCK supplies excavator undercarriage parts through its appointed dealer network and quotes on request. If you are looking for Caterpillar, Komatsu, or other OEM-branded machines, VANROCK is an independent manufacturer and is not affiliated with those OEMs.
