Description
Overview:
This Roller, Carrier is a genuine Kubota undercarriage component designed to support the upper run of the rubber or steel track, keeping it aligned and running smoothly under load. Built from high-strength, wear‐resistant steel with a precision‐machined running surface, it is engineered to cope with impact, abrasion, and continuous duty on site. A sealed design helps keep out dirt and moisture to protect the internal bearing surfaces and reduce maintenance. It is a direct fit on popular Kubota mini excavators such as the KX040-4 and KX057-5, ensuring correct geometry and reliable tracking. As an OEM part (RD461 21950), it matches factory specifications for fit and performance, helping extend track life and minimise downtime on construction, landscaping, utilities, and groundworks.
Key Features:
- Genuine Kubota OEM carrier roller for assured compatibility and quality (OEM No. RD461 21950)
- High-strength, heat-treated steel body for durability in abrasive and high‐impact conditions
- Sealed-for-life design helps protect bearings from mud, water, and grit to reduce maintenance
- Precision fit on specified models for straightforward replacement using standard tools
- Helps maintain track alignment and smooth travel, reducing vibration and wear on the undercarriage
- Robust load capacity suitable for continuous use on hardstanding, clay, and mixed terrain
- Consistent performance in UK weather conditions and site environments
- Supports planned maintenance schedules to cut unplanned downtime
Typical Applications:
Use during routine service or repairs on Kubota mini excavators working in construction, utilities, landscaping, groundworks, and plant hire. Ideal when tracks are showing uneven top-run support, excessive vibration, or roller wear, restoring smooth travel and helping protect sprockets, idlers, and track chains in daily operations.
