Key Features

• Heavy-Duty Construction: Forged steel roller body with a hardened wear surface to handle harsh, abrasive ground conditions and high load cycles.
• Oil-Filled, Sealed Design: Internal bearings run in oil with multi-lip seals to keep grease and oil in, and dust, mud, and water out for long service life.
• Smooth, Stable Tracking: Supports the upper section of the rubber track to reduce sag, improve tracking, and minimise stress on sprockets and idlers.
• Low Maintenance: Maintenance-free sealed unit—no daily greasing required, just periodic visual inspection as part of your undercarriage checks.
• Direct-Fit Replacement: Built to OEM-style dimensions for quick bolt-on replacement using standard tools.

Product Warranty

All excavator top rollers include a 1-year warranty, covering manufacturing defects to give you confidence and peace of mind on every job.

How to Confirm the Correct Top Roller

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.
