PRODUCT DESCRIPTION

This track roller is a key component for the Kubota KX033-4 mini excavator chassis, part number RC788-21700. As a must-have accessory in the European and American markets for 2025-2026, this KX033-4 track roller is specifically designed for the Kubota KX033-4 mini excavator. It uses the original part number RC788-21700 and is compatible with multiple replacement part numbers. It is a genuine Mini Excavator Undercarriage Part, allowing for direct replacement with the original parts and error-free installation.

This Kubota KX033-4 track roller features a double-flange reinforced structure and a lifetime lubrication seal. It precisely matches the original rubber tracks of the KX033-4, ensuring stable movement and effectively preventing track deviation and derailment, significantly improving the stability and efficiency of the mini excavator.

The wheel body is made of high-strength alloy steel, using a closed-loop forging and overall heat treatment process. The tread surface is strengthened by high-frequency quenching, achieving a surface hardness of HRC52-58 and a hardened layer of 7-10mm. It boasts superior wear resistance, impact resistance, and fracture resistance, perfectly suited for complex and harsh working conditions in European and American gardens, municipal projects, farmland, and rental construction sites. The core axle is made of alloy tempered steel, offering high toughness and wear resistance during rotation. Internally, it features heavy-duty bearings and a multi-labyrinth floating seal system, preventing dust, water, and mud intrusion, completely resolving issues like oil leakage, mud ingress, and premature wear in track rollers.

It comes pre-filled with long-lasting high-temperature grease, featuring a fully enclosed, maintenance-free structure, reducing subsequent maintenance costs. Standard precision dimensions ensure easy installation and high interchangeability. Each wheel has a moderate weight and fine workmanship. Custom black or yellow engineering paint finishes are available for enhanced corrosion and rust resistance and outdoor weather resistance.

The entire series is ISO9001 certified, ensuring stable and reliable quality. A 2000-hour warranty is provided under normal operating conditions. As a core component of Kubota mini excavator replacement parts, we support OEM/ODM customization, FOB Xiamen shipping, stable delivery times, and significant price advantages, along with comprehensive after-sales technical support.

Focusing on the essential needs of the European and American mini excavator aftermarket, the KX033-4 heavy-duty wheels have a large circulation volume and high repurchase rate. They are currently a high-volume chassis wear part for Kubota's 3-ton mini excavator repair and replacement, overseas bulk stocking, and export sales.
