Key Features
- Heavy-Duty Load Bearing: Robust forged steel roller body and high-strength shaft designed to support full machine weight and absorb dynamic impact loads.
- Hardened Wear Surfaces: Induction-hardened tread and flanges to resist abrasion from rocks, dirt, and debris, extending roller and track life.
- Oil-Filled, Sealed Design: Internal bearings run in oil with multi-lip seals to retain lubrication and keep dust, mud, and water out for long service intervals.
- Straight, Stable Tracking: Supports and guides the lower track to reduce derailment risk, improve operator comfort, and minimise stress on sprockets and idlers.
- Low Maintenance: Maintenance-free sealed unit—no daily greasing required, only periodic visual checks as part of your undercarriage inspection.
- Direct-Fit Replacement: Built to OEM-style dimensions for fast bolt-on replacement using standard workshop tools.
Product Warranty
All excavator bottom 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 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.
