Compatible with a wide range of mini excavator makes and models. Contact us if you need help confirming the correct top roller for your machine.
All excavator top 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 excavator’s make, model, and serial number, and where possible compare the existing roller’s dimensions (overall length, flange-to-flange distance, and shaft diameter) with our specifications before ordering.
If you are unsure, contact us with a photo of your current roller and your machine ID plate and we can help match the correct part.

Extend your undercarriage life and reduce downtime with durable, reliable top rollers purpose-built for tough Australian worksites.
