Heavy-Duty Excavator Drive Sprockets & Segment Group Replacements

If you've noticed your sprocket teeth becoming thin or "hooked," or if your machine is struggling to climb, it’s time for a replacement drive sprocket. As the final link in your power train, the drive wheel must perfectly mesh with your track links to ensure smooth travel. BeeSpareParts offers precision-cast and forged sprocket rims and segment groups designed to handle the high-torque demands of heavy excavation.

Using a worn sprocket with a new track chain is a common mistake that causes premature failure. To maximize your undercarriage life, we strongly recommend replacing your at the same time, or inspecting your if you notice oil leaking near the drive. Our heavy-duty sprockets are direct-fit alternatives to OEM parts, featuring deep induction hardening (HRC 50+) on the tooth profiles to resist abrasive wear from mud and sand.

Whether you need a sprocket for a 20-ton Komatsu, a bolt-on segment for a Cat, or a mini-excavator drive wheel, our parts are factory-tested for pitch accuracy and ready for fast international shipping. Restore your machine's pushing power—order your premium sprocket solutions today.
