Compatible with a wide range of mini excavator makes and models. Contact us if you need help confirming the correct bottom roller for your machine.
All excavator bottom rollers include a 1-year warranty, covering manufacturing defects to give you confidence and peace of mind on every job.
To ensure proper fitment, confirm your excavatorβs 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.
