Product Warranty

How to Confirm the Correct Bottom Roller

To ensure proper fitment, confirm your excavator’s make, model, and serial number, and where possible measure your existing bottom roller (overall length, flange-to-flange distance, body diameter, and shaft diameter) and compare with our specifications before ordering.

If you are unsure, contact us with photos of your current bottom rollers installed on the track frame, plus a photo of your machine ID plate, and we can help match the correct part.
